My HP-UX 11.00 system doesn't use "__size_t" in any headers.  It
appears that there are a variety of different header configuration
for 11.00.

Under the HP-UX 11.11, the only headers which define __size_t are
varargs.h and sys/stdsyms.h.  __size_t is used in pwd.h, stdio.h,
stdlib.h, string.h, wchar.h, sys/newsig.h, sys/time.h, and sys/unistd.h.

Yes.

Gcc 3.1 seems to work ok without this hack on 11.11, albeit with only
a limited amount of testing (haven't tried C++ yet).  Could you provide
a specific test case where you have a problem without your hack?  I
tried including stddef.h with the headers which use __size_t and didn't
see a problem, either with stddef.h first or last.
