In the mips--netbsdelf target gcc 4.9 lost the pre-definition of
__mips_o32, which is heavily used in NetBSD sources.

The obvious trivial patch adds it back.

Define __mips_o32 for -mabi=32

Are you sure it was ever in FSF GCC?  I went through every revision
of netbsd.h in git and couldn't see it.

I can go ahead and apply the patch anyway if it's the right thing to do.
Just wanted to make sure I wasn't missing something.

Thanks,
Richard

No, I'm not - guess I never tried a pure gcc on mips.

Matt Thomas should be the authority on this. This was one of the very
few changes I needed so far for NetBSD/playstation2 (the others all in
bugzilla already).

Matt?

OK, in that case I went ahead and applied it.  Thanks for the patch.
