* Makerules (lib%.so: lib%_pic.a): Pass -soname switch giving the library's name including $(libprefix) and major version number. * locale/locale-ctype.c (allocate_arrays): Use xmalloc and bzero in place of xcalloc. * Makeconfig (prefix, exec_prefix, libprefix): Instead of `ifndef', use the $(origin) function to only set these if they are undefined, and not if they are defined to empty. * gnu-versions.h: New file. * features.h (__GNU_LIBRARY__): Increase value to 5.
