Patches to calls(1) for 4.2 BSD

[sources-request at panda.UUCP]

Mod.sources:  Volume 3, Issue 48
Submitted by: The Heliopolist  <talcott!seismo!rochester!ken>


I had to make a couple of small changes to calls.c to compile under 4.2
BSD. Also the Makefile need to be edited to include getopt.o.

	Cheers, Ken
