	I am actually evaluating GNU-C++ (g++) compiler on SUN platform.
The problem that arise is using SUN header with g++. It is impossible
to use .h in /usr/include since they have standard c declaration. If
you are using g++ with Sunview and eventually OpenWIN, what have you 
done about it?



	I have also found that incompatibilite when mixing Sun header file
with g++ (they were others wich were easy to correct)

-----------------------------------------------------------------------
#ifndef	CAT
#undef	IDENT
#define IDENT(x)	x
#define	CAT(a,b)	IDENT(a)b
#endif

#define mpr_static(name, w, h, d, image) \
	struct mpr_data CAT(name,_data) = \
	    {mpr_linebytes(w,d), (short *)(image), {0, 0}, 0, 0}; \
	Pixrect name = {&mem_ops, w, h, d, (caddr_t)&CAT(name,_data)}

-----------------------------------------------------------------------

	g++ can't expand that macro (wich work fine with sun compiler of course)
giving a parse error before _data. Anyone have a modification i could
apply to solve the problem.
