You are correct. It is not C99 specific. I was quoting the C99 standard
which Bruno referenced to be sure everyone was on the same page because

Yes, it was wrong. Thank you for noticing the problem.
I changed it to ((size_t)~(size

Yes. As explained on 2005-07-11, I prefer to write this as
((size_t)~

No. I suspect he's been busy. Now that you've pinged him again let's
give him another chance for a few days; if he doesn't respond I don't
think he'd object to that patch.

Hi Paul,
Did Bruno ever give you his opinion for this fix?
Thanks,

Yes, that's true. There are several other deficiencies like that in
stdint_.h.
I wonder why stdint_.h diverges so much from

Does the following (untested) patch fix things for you?
2005-11-14 Paul Eggert <[EMAIL PROTECTED]>
* lib/stdint_.h (intmax_t) [defined intmax_t]: Do not declare.
(uintmax_t) [defined uintmax_t]: Do not declare.
This works around a problem if intmax_t.m4 and/or uintmax_t.

I have run into a quirk of GNULIB building CVS on a FreeBSD 4.2 host.
It seems that CVS is using m4/intmax.m4 which generate these lines
into the config.h file:
/* Define if you have the 'uintmax_t' type in or . */
/* The size of a `intmax_t', as co
16 matches
