libmudflap.exp (libmudflap-init): For C++ test cases only...

2004-05-17  Frank Ch. Eigler  <fche@redhat.com>

	* lib/libmudflap.exp (libmudflap-init): For C++ test cases only,
	import some build settings from libstdc++-v3 testsuite_flags.
	* .../cfrags.exp, .../c++frags.exp, .../cthfrags.exp: Corresponding
	changes to pass test language.

	* mf-runtime.c (__mfu_check): Poison the cache with antidote for
	quicker mode-nop handling.
