2000-10-30 Phil Edwards <pme@sources.redhat.com> * acinclude.m4 (GLIBCPP_ENABLE_DEBUG): Raise debugging level from the default of 2 to 3. * configure.in: Fix minor typos. SUBST the values of enable_shared and enable_static so that mkcheck will be aware of them. Put the test for gconv.h in with all the other header tests. * aclocal.m4: Regenerate. * configure: Ditto. * Makefile.in: Ditto. * libio/Makefile.in: Ditto. * libmath/Makefile.in: Ditto. * libsupc++/Makefile.in: Ditto. * src/Makefile.in: Ditto. * config/os/solaris/solaris2.7/bits/os_defines.h: Define _G_USING_THUNKS to 0.
