--- Comment #1 from John David Anglin <danglin at gcc dot gnu.org> ---
Actually, the error was introduced by this change:
2015-05-26 Jason Merrill <ja...@redhat.com>
* configure.ac: When bootstrapping with GCC, add -std=c++98 to CXX.
* configure: Regenerate.
This affects the hpux11 builtin defines:
if (flag_pa_unix >= 1995 && !flag_iso) \
{ \
builtin_define ("_XOPEN_UNIX"); \
builtin_define ("_XOPEN_SOURCE_EXTENDED"); \
} \
Probably, we want the XOPEN stuff for c++98 and later, but the bootstrap
problem can only be fixed by changing bootstrap compiler. We get the "wrong"
declaration for nftw when _XOPEN_SOURCE_EXTENDED isn't defined. So, I think
a configure fix is needed.
I noticed in testing that -std=c++98 is not used in stage2 and we don't seem
to have the same language defaults there.
