Having suggested the same myself (see mod.std.c archives), I'll second the
motion. . .with a qualification.  Since there are existing (Whitesmiths)
implementations with an interface different from that described above, it's
almost surely best to use a different name for the above interface--for
example,

 	int atexit(void (*func)(void));

This avoids surprises when moving existing source code to an ANSI standard
system.
