Reply-To:	djgpp-workers AT delorie DOT com

This kills warnings under DJGPP about 'offsetof' redefinition.
Current system.h defines its own offsetof macro only if it hasn't
been defined previously. But before that, it #includes just <stdio.h>,
and according to ANSI, offsetof lives in <stddef.h>. 

This patch includes <stddef.h> (if configure script has found it)
before offsetof and NULL fallback definitions.

	* system.h: #include <stddef.h> if HAVE_STDDEF_H defined.
