If the compiler gets something trivial like this wrong it is going to kick you in other areas (I assume that by 'check' you mean comparison i.e. a context where the type required is unambiguous). If you're that mistrustful of C compilers I suggest you change languages! The C language has always made pointer comparison against 0 well defined so even a non-ANSI compiler should get this right. (Since others have remarked on a lack of references in my postings to comp.lang.c.moderated, which results in lack of threading, I'm trying this as a normal posting. In the past this hasn't worked too well here for moderated newsgroups hence I've been mailing my postings which fails to generate references). -- ----------------------------------------- Lawrence Kirby | fred@genesis.demon.co.uk Wilts, England | 70734.126@compuserve.com -----------------------------------------
