Version: fltk 1.1-r5691 svn / cygwin.

Summary: configure does not define U32 (and U16) in config.h

I've seen some more reports in fltk.general regarding this problem. It may
be related to a recent upgrade of autoconf, but I'm not sure. Previous
versions didn't show this problem. Configure output will be attached in
file autoconf_U32.txt. There are some warnings: ": integer expression
expected 2" and (4 times) ": integer expression expected 4".

I upgraded my cygwin version recently, and I think that the problem arised
after upgrading, even without changing the fltk sources.

Autoconf version is now 2.61, but I don't know the previous version that
worked. IIRC, 2.60 had the problem, too.

My linux box with autoconf 2.59d does define U16 and U32:

#define U16 unsigned short
#define U32 unsigned
/* #undef U64 */

but this might also be a system related issue.

If someone can help and needs more info, please ask for it. I can't see
anything strange in config.log.
