State-Changed-Why:
    I'm surprised that you are using --enable-cheaders=c. Please provide more details on how you got this working for NetBSD. It is not a supported default configuration, although it does work for some targets (newlib crosses, perhaps QNX.)
    
    In any case, this patch below should do the trick. If it doesn't, you'll have to add more description to your bug report, including compiler error, sample code that goes wrong, and includes used...

>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.
