The autoconf2.5 package contains the latest edition of autoconf in the 2.5x release sequence (which includes 2.60, 2.61, etc). This is the first release specific for cygwin-1.7; the major differences between this package and the simultaneously-released autoconf2.5-2.63-1 for cygwin-1.5 are documentation related (the README references cygport-0.9.2 and cygwin-1.7.0-30, and the /usr/share/doc/ layout is influenced by the cygport changes between 0.4.0 and 0.9.2). Changes (autoconf2.5-2.61-1 ---> autoconf2.5-2.63-10) * Fork from cygwin-1.5 package development stream * update to latest upstream release + see list of upstream changes below * requires autoconf-6-10 or better (wrapper) * Updated packaging to use stock cygport 0.9.2 rather than custom version of cygport. * Now includes emacs editing modes for autoconf and autotest * Removes /usr/share/doc/standards.info.gz + provided by binutils and cygwin so conflict still exists but at least autoconf will no longer complicate the situation. FWIW, most GNU/Linux distributions ship this file in binutils. + Users may need to re-install one of these other two packages to restore standards.info.gz. Test results: 361 tests behaved as expected. 3 tests were skipped. -- Charles Wilson autoconf volunteer maintainer for cygwin * Major changes in Autoconf 2.63 (2008-09-09) [stable] Released by Eric Blake, based on git versions 2.62.*. ==================================================================== ** AC_C_BIGENDIAN does not mistakenly report "universal" for some bigendian hosts, a regression introduced with universal binary support in 2.62. ** AC_PATH_X now includes /lib64 and /usr/lib64 in its list of default library directories. ** AC_USE_SYSTEM_EXTENSIONS no longer conflicts with an external AC_DEFINE([__EXTENSIONS__]). This fixes a regression introduced in 2.62 when using macros such as AC_AIX that were made obsolete in favor of the more portable AC_USE_SYSTEM_EXTENSIONS. ** AC_CHECK_TARGET_TOOLS is usable in the non-cross-compile case. ** Newly obsolete macros The following macro has been marked obsolete, since current porting targets can safely assume C89 semantics that signal handlers return void. We have no current plans to remove the macro. AC_TYPE_SIGNAL ** The macros m4_map and m4_map_sep now ignore any list elements consisting of just empty quotes, and m4_map_sep now expands its separator. This fixes a regression in 2.62 when these macros were first documented, for the sake of clients expecting the semantics that these macros had prior to that time. The new macros m4_mapall and m4_mapall_sep, along with extra quoting of the separator, can be used to get the semantics that m4_map_sep had in 2.62. ** Clients of m4_expand, such as AS_HELP_STRING and AT_SETUP, can now handle properly quoted but otherwise unbalanced parentheses (for some macros, this fixes a regression in 2.62). ** Two new quadrigraphs have been introduced: @{:@ for (, and @:}@ for), allowing the output of unbalanced parentheses in more contexts. ** The following m4sugar macros are new: m4_joinall m4_mapall m4_mapall_sep m4_reverse m4_set_add m4_set_add_all m4_set_contains m4_set_contents m4_m4_set_delete set_difference m4_set_dump m4_set_empty m4_m4_set_foreach set_intersection m4_set_list m4_m4_set_listc m4_set_remove set_size m4_set_union ** The following m4sugar macros now accept multiple arguments, as is the case with underlying m4: m4_defn m4_popdef m4_undefine ** The following m4sugar macros now guarantee linear scaling; they previously had linear scaling with m4 1.6 but quadratic scaling when using m4 1.4.x. All macros built on top of these also gain the scaling improvements. m4_bmatch m4_bpatsubsts m4_case m4_cond m4_do m4_dquote_elt m4_foreach m4_join m4_list_cmp m4_map m4_map_sep m4_max m4_min m4_shiftn ** AT_KEYWORDS once again performs expansion on its argument, such that AT_KEYWORDS([m4_if([$1], [], [default])]) no longer complains about the possibly unexpanded m4_if [regression introduced in 2.62]. ** Config header templates `#undef UNDEFINED /* comment */' do not lead to nested comments any more; regression introduced in 2.62. * Major changes in Autoconf 2.62 (2008-04-05) [stable] Released by Eric Blake, based on git versions 2.61a.*. ==================================================================== ** Many optimizations have been applied to make overall execution faster. ** Autotest now makes use of shell functions. ** config.status now uses awk instead of sed also for config headers. - As a side effect, AC_DEFINE and AC_DEFINE_UNQUOTED now handle multi-line values, i.e., backslash-newline combinations are handled correctly. Further, for config headers, the total size of values is not limited by the POSIX length limit of text lines any more, only each single line. ** New config variable `top_build_prefix'. ** New Autoconf macros: AC_AUTOCONF_VERSION AC_OPENMP AC_PATH_PROGS_FEATURE_CHECK ** AC_C_BIGENDIAN now supports universal binaries a la Mac OS X. ** AC_C_RESTRICT now prefers to #define 'restrict' to a variant spelling like '__restrict' if the variant spelling is available, as this is more likely to work when mixing C and C++ code. ** AC_CHECK_ALIGNOF's type argument T is now documented better: it must be a string of tokens such that "T y;" is a valid member declaration in a struct. ** AC_CHECK_SIZEOF now accepts objects as well as types: the general rule is that sizeof (X) works, then AC_CHECK_SIZEOF (X) should work. ** AC_CHECK_TYPE and AC_CHECK_TYPES now work on any C type-name; formerly, they did not work for function types. In C++, they now work on any type-id that can be the operand of sizeof; this is similar to C, except it excludes anonymous struct and union types. Formerly, some (but not all) C++ types involving anonymous struct and union were accepted, though this was not documented. ** AC_CONFIG_LINKS now prefers to link against files in the build tree if found, and it works to link against a file of the same name in the source tree, even if both trees coincide. ** AC_INIT no longer alters $@; regression introduced in 2.60. ** AC_USE_SYSTEM_EXTENSIONS now defines _ALL_SOURCE for Interix platforms. ** AS_HELP_STRING no longer underquotes its first argument; it also handles the case where the first argument contains single-quoted commas. For example, "AS_HELP_STRING([-a, [--arg[=foo]]], [bar])" produces: " -a, --arg[=foo] bar" Additionally, the macro now takes two additional arguments, indent-column and wrap-column; these should not normally be needed, but can be used to fine-tune how the output text is wrapped. ** AC_PROG_INSTALL now requires an install program that can install multiple files into a target directory. ** The command 'autoconf -' now correctly processes a file from stdin. ** 'autoreconf -m' now honors $MAKE. ** For all of the directory arguments for 'configure', such as '--prefix' or '--bindir', trailing slashes are stripped. As an example, if tab completion in the user's shell appends trailing slashes, the command './configure --prefix=/usr/' will still result in an expanded libdir value of /usr/lib, not /usr//lib. ** `configure --help=recursive' now works in read-only trees and from unconfigured build trees. ** If precious variables differ only in whitespace, then the cache consistency heck warns instead of fails, and reuses the cold value. ** AT_BANNER is now documented. ** AT_SETUP now handles macro expansions properly when calculating line length. ** Autotest now determines $srcdir correctly. ** Testsuites built by autotest now accept a -C/--directory=DIR option to adjust the working directory prior to creating files. ** Autoconf now requires GNU M4 1.4.5 or later. Earlier versions of M4 have a bug in macro tracing that interferes with the interaction between Autoconf and Automake. GNU M4 1.4.11 or later is recommended. The configure search for a working M4 is improved. ** For portability with the eventual M4 2.0, macros should no longer use anything larger than $9 to refer to arguments. ** Documentation for m4sugar is improved. - The following macros were previously available as undocumented interfaces; the macros are now documented as stable interfaces. __oline__ m4_assert m4_bmatch m4_bpatsubsts m4_car m4_case m4_cdr m4_default m4_divert_once m4_divert_pop m4_divert_push m4_divert_text m4_do m4_errprintn m4_fatal m4_flatten m4_ifndef m4_ifset m4_ifval m4_ifvaln m4_location m4_n m4_shiftn m4_strip m4_warn - The following macros were previously available as undocumented interfaces, but had bug fixes or semantic changes as part of this release. Packages that relied on the undocumented behavior should be analyzed to make sure they will still work with the new documented behavior. m4_cmp m4_list_cmp m4_join m4_map m4_map_sep m4_sign m4_text_box m4_text_wrap m4_version_compare - The m4_wrap macro used to have unspecified order, but now guarantees FIFO order. m4_wrap_lifo was added to guarantee LIFO order. - Packages using the undocumented m4sugar macro m4_PACKAGE_VERSION should consider using the new AC_AUTOCONF_VERSION instead. - m4sugar macros that are not documented in the manual are still deemed experimental, and should not be used outside of Autoconf. ** The m4sugar macros m4_append and m4_append_uniq, first documented in 2.60, have been fixed to treat both the string and the separator arguments consistently with regards to quoting. Prior to this fix, m4_append_uniq could mistakenly duplicate entries if the expansion of the separator resulted in a different string (for example, if it contained quotes, a comma, or a macro name). However, it means that programs previously using m4_append([name], [string], [[, ]]) are now using a four-character separator instead of the intended comma and space. If you need portability to earlier versions of Autoconf, you can insert the following snippet after AC_INIT but before any other macro expansions, to enforce the new semantics: m4_pushdef([m4_append], [m4_define([$1], m4_ifdef([$1], [m4_defn([$1])[$3]])[$2])]) Additionally, m4_append_uniq now takes optional parameters that can be used to take action depending on whether anything was appended, and warns if a non-empty separator occurs within the string being appended, since that can lead to duplicates. ** The following m4sugar macros are new: m4_append_uniq_w m4_apply m4_combine m4_cond m4_count m4_dquote_elt m4_echo m4_expand m4_ignore m4_make_list m4_m4_max min m4_newline m4_shift2 m4_shift3 m4_unquote m4_m4_wrap_lifo ** Warnings are now generated by default when an installer invokes 'configure' with an unknown --enable-* or --with-* option. These warnings can be disabled with the new AC_DISABLE_OPTION_CHECKING macro, or by invoking 'configure' with --disable-option-checking. ** Existing obsolete macros The documentation for the following macros is adjusted to make it more clear that they have previously been marked obsolete, as their functionality can be accomplished by other macros. We have no current plans to remove them from Autoconf. AC_ENABLE AC_STRUCT_ST_BLKSIZE AC_STRUCT_ST_RDEV WITH ** Newly obsolete macros The following macros have been marked obsolete, as they only perform a subset of AC_USE_SYSTEM_EXTENSIONS. We have no current plans to remove them. AC_AIX AC_GNU_SOURCE AC_ISC_POSIX AC_MINIX ** AC_C_LONG_DOUBLE is obsolescent. The documentation now says that AC_C_LONG_DOUBLE is obsolescent: it tests for problems that are so old that it is no longer of practical importance on current systems. New programs need not use AC_C_LONG_DOUBLE. We have no current plans to remove it. ** AC_DIAGNOSE, AC_WARNING, and AC_FATAL are obsolescent. The documentation now favors the use of M4sugar macros m4_warn and m4_fatal, since the naming makes it more obvious that the diagnostics are associated with M4 expansion (ie. when running `autoconf'), and offers less confusion with the AC_MSG_ERROR, AC_MSG_FAILURE, and AC_MSG_WARN macros which manage diagnostics when running `configure'. We have no current plans to remove these macros.
