 I think it would be better to write something like:

#if HELL != FROZEN
	for(;;)    /* or while(1) if you prefer */
		... do whatever
#endif

 This has the advatge that lint (at least some lints) won't warn you for
unreachable code. I also think, but this is a personal opinion, that it is
clearer.

ps. Concerning while(1) and for(;;). My old CP/m C-compiler (Digital Research)
used to have the declaration:

#define	forever()	for(;;)

 in portab.h. I agree that for(;;) is ugly, but somehow I don't think while(1)
look good either.
