Apologies if this is a FAQ.

There seem to be major type clashes between gcc (specifically
stddefs.h, but possibly also internaly) and the Sun supplied header
files for SunOs 4.1

All of the errors seem to localise to the sun header sys/systypes.h
which defines things like size_t in a way which clashes with
stddefs.h. This makes life dificult when trying to compile anything
even vaguely ANSIised. 

So, two questions:

	1: Is there a relatively neat work-around which we can include
	in our system without making the people we deliver it to ill?

	2: If we end up changine headers, which way is least likely to
	cause death and mayhem, changing gcc's headers to conform to
	suns or creating a gcc specific version of sun's header with
	the gcc definitions in it.

particularly worrying, though not directly a problem for us, is the
fact that gcc and SunOs have a totally different idea of how big a
wide character is.

rjc@cstr.ed.ac.uk	Well, ok, so unsigned long vs long for size_t 
			will _probably_ never cause problems, except
			in my aesthetics...
