ctype support.
2004-06-09 Frank Ch. Eigler <fche@redhat.com>
ctype support.
* configure.in: Look for ctype header and glibc implementation.
* mf-hooks2.c (__ctype_{b,toupper,tolower}_loc): Sample ctype
array hooks for glibc 2.3.
* mf-runtime.h.in: Wrap them.
* mf-runtime.c (__mf_init): Leave marker regarding other ctype
implementations.
* testsuite/libmudflap.c/pass47-frag.c: New test.
* configure, config.h.in: Regenerated.
