>Description:
	The following change (and its related changes) prevents libstdc++
	from being built on NetBSD since NetBSD does not use GLIBC but does
	define its own mbstate_t.  Thus mbstate_t defined typedefed twice
	and libstdc++ fails to build.

        * include/c/std_cwchar.h: Guard. Add mbstate_t bits.
        * include/c/std_cwctype.h: Guard.

        * libsupc++/eh_alloc.cc: Tweak include order.
        * libsupc++/pure.cc: Use cstdio.
        * libsupc++/new_op.cc: Remove malloc forward declaration, as
        cstdlib brings it in. Use std::malloc.

        * src/Makefile.am (sources): Remove cmath.cc.
        * src/Makefile.in: Regenerate.
        * src/cmath.cc: Remove.
