Well, I was hoping for some feedback as to whether changing wint_t to be
signed was preferable over changing WINT_MIN.  But further research shows
Linux also uses an unsigned type for wint_t, so:

I sent in the copyright assignment paperwork for this around two weeks 
ago...just wanted to follow up to see if that was ever received, and if 
so, if this patch can be committed or needs further work.

Thanks,

Sorry, I didn't get the note from our dept so far.  I'll investigate...

Chris, are you going to review the patch?

Thanks,

Actually, I'd appreciate it if the patch could be resubmitted against
current CVS.

A two-line patch, and I _still_ managed to botch it.  POSIX requires that
WINT_MIN be unsigned if (wint_t)0 promotes to an unsigned type.

Or in other words, (-1 < WINT_MIN) == ((wint_t) -1 < 0) must be true.

	* include/stdint.h (WINT_MIN): Fix sign.
