This appears to be a glibc >= 2.10 platform, right? I reproduce it on a RHEL 6 system. The issue appears to be the same as the two problems in <http://lists.gnu.org/archive/html/bug-gnulib/2010-03/msg00113.html> <http://lists.gnu.org/archive/html/bug-gnulib/2010-03/msg00125.html> and is caused by this commit in glibc: <http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=d8387c7b7b1c9ae92f924c33ba05790c98464d19> I'm committing this fix: 2011-04-01 Bruno Haible <br...@clisp.org> wmemchr, wcschr, wcsrchr, wcspbrk, wcsstr: Avoid errors in C++ mode. * lib/wchar.in.h (wmemchr, wcschr, wcsrchr, wcspbrk, wcsstr): Use _GL_CXXALIAS_SYS_CAST2 instead of _GL_CXXALIAS_SYS. On glibc >= 2.10 systems, use _GL_CXXALIASWARN1 instead of _GL_CXXALIASWARN.
