I have bisected the problem using the git gcc repository, unfortunately 121
commits are left after bisecting, as in between the last known good and the
first known bad commit the gcc tree does not compile for a lot of commits.

Anyway, this is the last known good commit:

commit 244de65defd519a1245551886fce58113a4b7b2a
Author: charlet <charlet@138bc75d-0d04-0410-961f-82ee72b054a4>
Date:   Wed Jun 6 10:13:25 2007 +0000

This is the first known bad commit:

commit 7b29e7de1cf940343eeeb25058b7870877d15524
Author: charlet <charlet@138bc75d-0d04-0410-961f-82ee72b054a4>
Date:   Wed Jun 6 10:54:04 2007 +0000

The 120 commits in between do not compile, and all do massive changes in the
Ada part of gcc.

--- Comment #7 from Markus Eisenmann <meisenmann.lba@fh-salzburg.ac.at> 2013-04-17 09:17:36 UTC ---
At least this error is based on some libintl-macros, which will "redirect" some
stdio-functions (like vsnprintf ...) to their libintl-version(s); I.e. the
header-file libintl.h is available and included, but NLS/libintl isn't
requested.

Solution (as be possible by processing the attached patch/diff-file):

Add following undef's in the #else-region of gcc/intl.h (of #ifdef ENABLE_NLS),
for example after line #54:

#undef    fprintf
#undef    vfprintf
#undef    printf
#undef    vprintf
#undef    sprintf
#undef    vsprintf
#undef    snprintf
#undef    vsnprintf
#undef    asprintf
#undef    vasprintf
#undef    setlocale

Additional comment:
The header-file gcc/intl.h does already contain undef's to prevent using
libintl if not requested or configured. But not for the affected "stdio-funcs"
as vsnprintf [...], which may cause linker-errors (I.e. unresolved externals).
