acconfig.h: Update comments.
2001-11-02 Phil Edwards <pme@gcc.gnu.org>
* acconfig.h: Update comments.
* acinclude.m4 (GLIBCPP_ENABLE_C99): Move strtoll, strtoull tests...
(GLIBCPP_ENABLE_LONG_LONG): ...to here. Don't check enable_c99.
* aclocal.m4: Regenerate.
* config.h.in: Regenerate.
* configure: Regenerate.
* include/bits/boost_concept_check.h: Unconditionally compile uses
of 'long long' which require only compiler support, not C lib support.
* include/bits/cpp_type_traits.h: Likewise.
* include/bits/std_limits.h: Likewise.
* include/bits/type_traits.h: Likewise.
* src/concept-inst.cc: Likewise.
* src/limits.cc: Likewise.
* include/c_shadow/stdlib.h: Compile conditionally on _GLIBCPP_USE_C99
instead of _GLIBCPP_USE_LONG_LONG.
* include/c_shadow/bits/std_cstdlib.h: Likewise.
