* configure.ac: Check gcc and g++ for -fvisibility and -fvisibility-inlines-hidden. Add these options to CFLAGS and CXXFLAGS. * m4/ax_check_compile_flag.m4: New file. * src/Makefile.am: Build BuDDy as a single library, reverting part of the changes introduced in my previous patch to this file. Since the options are set in CFLAGS/CXXFLAGS, there is no possibility for -fvisibility-inlines-hidden to be passed to the C compiler.
