2008-04-24 Benjamin Kosnik <bkoz@redhat.com>
PR libstdc++/35887
* configure.ac: Add default argument to GLIBCXX_ENABLE_PARALLEL.
Move atomic warnings to GLIBCXX_ENABLE_ATOMIC_BUILTINS.
* acinclude.m4 (GLIBCXX_ENABLE_PARALLEL): Check for --disable-libgomp.
(GLIBCXX_ENABLE_ATOMIC_BUILTINS): Add warning information.
* configure: Regenerate.
* include/Makefile.am (parallel_headers): Make conditional on
ENABLE_PARALLEL.
* include/Makefile.in: Regenerate.
