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.
