Fix alpha, powerpc build failures.
2000-06-21 Benjamin Kosnik <bkoz@soma.redhat.com> Fix alpha, powerpc build failures. * acinclude.m4 (GLIBCPP_CHECK_MATH_SUPPORT): Substantially re-write. Need to check for both proper declaration when using a c++ compiler, and "C" linkage when linking. Do both, and if both exist, then define the HAVE_* bits in config.h. (GLIBCPP_CHECK_MATH_DECL_AND_LINKAGE_n): New, uber-macros. Does all. (GLIBCPP_CHECK_LINKER_FEATURES): Actually link and run this program, doh. From-SVN: r34643
