>Description:
	/src/gnu/usr.bin/rcs fails to compile.
	The specific problem is an inconsistentcy in the (perfectly
	reasonable) declaration of _exit in src/rcs/lib/conf.h.
	This declaration is treated by gcc 2.5.8 as _incompatible__
	with the declaration in /usr/include/stdlib.h. The NetBSD
	native declaration has GNU CC attributes that GCC treats
	as incompatible with the simpler declaration.

>How-To-Repeat:

	(cd /src/usr.bin/gnu/rcs ; make)
	Where cc is, or is derived from, gcc 2.5.8.
	The NetBSD ``official'' release of GCC distributed with NetBSD
	may or may not have the same problem; I dont have access to
	a machine on which it builds.
>Fix:
	The following patch works for me, though I expect this same
	problem to occur with other ``portable'' software packages.
	I wonder if the declaration in stdlib.h is worth the cost.
	Perhaps submitting a GCC bug report requesting that the error
	be made a warning is the best thing?
