Hi Matthew,

The ctype_base.h file in libstdc++-v3 is out of date for NetBSD. They
have changed their ctype.h definition. It was updated in their intree
libstdc++-v3 but not in the GCC one. My understanding is this is a
straightforward rewrite. I've attached my own patch, but the file can
be obtained directly here:
http://cvsweb.netbsd.org/bsdweb.cgi/src/external/gpl3/gcc/dist/libstdc%2b%2b-v3/config/os/bsd/netbsd/ctype_base.h
With the attached patch, libstdc++-v3 can succesfully be built with
NetBSD headers (along with --disable-libcilkrts).
I noticed this has not been applied yet, nor seen a follow-up?, and also
noticed it went to the gcc-patches list, but not libstd...@gcc.gnu.org.
Let me re-address this to libstd...@gcc.gnu.org in the hope the
maintainers there will have a look.

I seem to recall looking at this previously and noting that the change
to ctype_base::mask is an ABI break. It means that code compiled with
old versions of GCC or on old versions of NetBSD will not be ABI
compatible with code compiled by a new GCC on a new version of NetBSD.
If the NetBSD maintainers are OK with that, then we can go ahead and
change it.
