I'm pretty sure the gcc distribution is not installed correctly, because your
problems are symptomatic of not having run "make install-fixincludes" at the
end of your gcc 2.3.3 installation process.

If you had, your compilations would be including

/usr/local/lib/gcc-lib/sparc-sun-sunos4.1.2/2.3.3/include/sys/stdtypes.h

instead of /usr/include/sys/stdtypes.h (as per your messages above).  By
running "fixincludes", it would have created a modified <sys/stdtypes.h> in
the gcc includes directory that contains (at the end)

...
#ifndef _GCC_SIZE_T
#define _GCC_SIZE_T
typedef	int		size_t;		/* ??? */
#endif
#ifndef _GCC_PTRDIFF_T
#define _GCC_PTRDIFF_T
typedef int		ptrdiff_t;	/* result of subtracting two pointers */
#endif

#ifndef _GCC_WCHAR_T
#define _GCC_WCHAR_T
typedef	unsigned short	wchar_t;	/* big enough for biggest char set */
#endif

#endif	/* !__sys_stdtypes_h */

This would have prevented the inclusion (in <stddef.h>) of the various
redeclarations of size_t, ptrdiff_t, wchar_t et al. because "_GCC_SIZE_T" et
al. would have been defined, and the code in gcc's <stddef.h> that checks for
these being set would have caused the redefines to be skipped over.
