When compiling oleo 1.2 (GCC 2.3.3, SunOS 4.1.2), I got the following
warning messages:

eval.c: In function `math_sig':
eval.c:1496: warning: `return' with a value, in function returning void
io-utils.c: In function `ignore_sig':
io-utils.c:85: warning: `return' with a value, in function returning void

Here is a patch.


Thu Dec 31 13:16:32 1992  Paul Eggert  (eggert@twinsun.com)

	* sysdef.h (SIGRET): Remove.  All invokers removed.
	This change might cause some harmless compiler warnings in
	old-fashioned hosts where signal functions yield `int', but
	that's better than always generating warnings in modern hosts
	where signal functions yield `void'.
