[Bug libstdc++/19656] New: libstdc++ testsuite results differ if bootstrap gcc 4.0 using some gcc 4.0 version or early (gcc 3.4.3) gcc version at FreeBSD

[wanderer at rsu dot ru]

If i bootstrap using installed some old or same CVS mainline gcc (a.k.a. gcc 
4.0.0) i have in testsuit results:

                === libstdc++ Summary ===

# of expected passes            3472
# of unexpected failures        1
# of unexpected successes       1
# of expected failures          5

If i bootstrap using gcc 3.4.3 version i have in testsuit results:

                === libstdc++ Summary ===

# of expected passes            3454
# of unexpected failures        10
# of unexpected successes       1
# of expected failures          5

contrib/compare_tests output:

Tests that now fail, but worked before:

Actually this looks like it is picking up a different libiconv rather than anything else.

Yes, the issue involves how the compiler used to bootstrap stage 1 is configured
and itself installed (is it in /usr/local? what ports have headers installed
there?).  On FreeBSD 5.3, I see this problem when I bootstrap 3.4.X with the
system compiler.  I do not see it when I bootstrap mainline with the system
compiler.  However...

BTW, adding --with-included-gettext seems to help me bootstrap mainline when the
status of installed ports and the stage 1 compiler is unknown.  Sorry, someone
would have to find the exact configuration patch that broke this and work with
the author of that change.

In m case used gcc configure options:
$(HOME)/pkg/build/gcc/src/gcc/gcc/configure                   --
prefix=$(HOME)/pkg/gcc --enable-threads=posix --with-gnu-as --with-gnu-ld --
enable-languages=c,c++

/usr/local/include/libintl.h exist.

Result my "find the exact configuration patch that broke this":

gcc mainline bootstraped using FreeBSD 5.3 system compiler (gcc 3.4.2) display 
error "cc1: no iconv implementation, cannot convert from ISO8859-1 to UTF-8" at
"-finput-charset=ISO8859-1" use always starting from adding -finput-charset 
option to gcc CVS mainline (2004-02-02 20:20 GMT).

I found problem:

At FreeBSD intl.h placed in /usr/local/include
and gcc 3.4.* not search by default /usr/local/include for system headers
(I check this for system compiler gcc version 3.4.2 [FreeBSD] 20040728 and gcc 
3.4.3)

gcc/intl/configure check intl.h by run test with command line: 
gcc -o conftest -g -O2   conftest.c  1>&5
and fail.

As result if gcc 4.0 bootstrap using gcc 3.4.* we have 
gcc 4.0 with disabled intl support :(((

And PR18360 indeed related to this bug report.

If gcc 3.4.3 bootstraped using installed gcc 4.0:

gcc/intl/configure test using gcc 4.0 and found /usr/local/include/libintl.h
and remember this

But stage1 gcc 3.4.3 not search in /usr/local/include and fail compile stage2 
with error:

In file included from c-parse.y:42:
/home/wanderer/pkg/build/gcc/src/gcc_34/gcc/gcc/intl.h:31:21: libintl.h: No 
such file or directory

I think rebuilding gcc/intl before each stage using previous build C compiler 
can fix PR19656 and PR18360

In --enable-bootstrap mode GCC doesn't have this problem (intl rebuild at each 
stage with --enable-bootstrap option).
