How have people been getting all these compilers to co-exist on the same
system ?   This would be on a Sun running SunOS 4.1.

Sun 4.1 cc
GNU gcc 1.38.90
GNU g++ 1.37.2
ATT C++ 2.1

This is what I've done in /usr/include/sys/stdtypes.h

#ifdef __cplusplus
typedef	unsigned int	size_t;		
#else
#ifdef __GNUC__
typedef	unsigned long	size_t;		
#else
typedef	int		size_t;		/* ??? */
#endif
#endif
#if defined (__GNUG__) || (__GNUC__)
typedef long int	ptrdiff_t;
#else
typedef int		ptrdiff_t;
#endif

Is there a cleaner way to do this?
