Not all targets reserve a bit for isblank, but this way ctype_base::blank is always defined, but on some platforms with the same value as ctype_base::space. That means that on those targets isblank(c, loc) is equivalent to isspace(c, loc) which is not correct, but isn't completely crazy either. Some systems (bionic, newlib, netbsd, openbsd) do define a _B (or _CTYPE_B) constant, but as it says on netbsd: /* * isblank() is implemented as C function, due to insufficient bitwidth in * _ctype_. Note that _B does not mean isblank - it means isprint && !isgraph. */ On those targets there is no bitmask corresponding to the isblank set. I don't know how to solve that without changing ctype_base::mask to a wider type, which I'm not planning on doing. N.B. on other BSDs (freebsd, darwin, dragonfly) _CTYPE_B *does* correspond to isblank. Portability is fun. Some implementations of ctype::is(mask, char) and/or ctype::do_is defined inline in config/os/*/ctype_inline.h need the ctype_base::blank mask, but those files get included by C++98 code, so for some targets ctype_base::blank is always defined even in C++98 mode. Solving that is too difficult. Tested x86_64-linux, with --enable-clocale={gnu,generic} and also by hacking configure.host to use config/os/generic, and also tested on x86_64-netbsd5.1 and x86_64-dragonfly3.6. Something will probably break on a target I didn't test, but should be easy to fix. I plan to commit this later today. --Fq7EdiloNwzjWdQG Content-Type: text/x-patch; charset=us-ascii Content-Disposition: attachment; filename="patch.txt" Content-length: 39119 commit 1c95ff5159b6a41e4f5f4d4919b8e394905bb9c4 Author: Jonathan Wakely Date: Thu Oct 16 15:21:02 2014 +0100 * src/c++98/Makefile.am: Move ctype.cc, ctype_configure_char.cc and ctype_members.cc to ... * src/c++11/Makefile.am: Here. * src/c++98/Makefile.in: Regenerate. * src/c++11/Makefile.in: Regenerate. * src/c++98/ctype.cc: Move file to ... * src/c++11/ctype.cc: Here, define ctype_base::blank. * config/abi/pre/gnu.ver: Export ctype_base::blank. * config/locale/generic/ctype_members.cc (ctype::_M_convert_to_wmask): Handle blank.
