Hmmm, I fail to see how the current implementation would differ from the one 
Detlev suggested:

"outcb" is initialised with either WATCHDOG_RESET or NULL in gunzip.c. Later 
on in zlib.c, the function referenced by outcb is called if not NULL. So those 
statements:

	if (strm->outcb != Z_NULL)
		(*strm->outcb)(Z_NULL, 0);

could be replaced by:

	WATCHDOG_RESET;

Perhaps I'm missing something?

Cheers,
Stefan
