Is this a 'make' bug?

I only did a quickworld this morning, which may have been a mistake.  When
I try a buildworld now it halts because of the generated file
/usr/obj/usr/src/btools_i386/usr/src/bin/csh/tc.defs.c which contains multiple
lines like this:

#if defined(mips) || defined(__mips)) && (defined(MIPSEL) || defined(__MIPSEL))

You can see there are two extra ')' characters in that line.  This error
happens with the new 'make' from this morning and also with the one from 04May.

If the typo was in libc/gen/ctype.c does that mean my existing copy of libc may
be causing this problem?

If so, I may be in deep doodoo because every part of world I try to compile now
stops with errors about unmatched or missing '(' characters.  I don't see a way
to rebuild libc, do you?
