compare.cc (test01): Add using declarations.

2000-10-23 Benjamin Kosnik <bkoz@redhat.com> * testsuite/21_strings/compare.cc (test01): Add using declarations. * include/c_std/bits/std_cerrno.h: And here. * include/c_std/bits/std_cassert.h: Tweaks. * mkcheck.in: Simplify. * acinclude.m4 (GLIBCPP_ENABLE_LONG_DOUBLE): Simplify. (GLIBCPP_ENABLE_LONG_LONG): Same. * aclocal.m4: Regenerate. * src/Makefile.am (c_shadow_headers): Add features.h, bits/wrap_features.h. * src/Makefile.in: Regenerate. * include/c_std/features.h: New file. * include/c_std/bits/wrap_features.h (_CPP_WRAP_FEATURES_H): New file. Need to have c++config.h included before this file so _ISOC99_SOURCE around. * include/c_std/sys/cdefs.h: Hack. * include/c_std/stdlib.h: Same, use c++config.h. * include/c_std/bits/std_cstdlib.h: Use _GLIBCPP_HAVE_STRTOLD. * include/c_std/bits/std_cassert.h: Fix. * include/c_std/bits/std_cerrno.h: Make consistent. * include/c_std/bits/std_csetjmp.h (setjmp): Unscope global declaration from ::_C_legacy to _C_legacy. * include/c_std/bits/std_cstdio.h: same with printf. * include/c_std/stdio.h: And here. * include/c_std/bits/std_cstdlib.h: abort, exit comment. * include/c_std/stdlib.h: Same here.
