log
@Minor rototill and respin patches; add patch comments, etc. I was taking
a shot at making it work on LP64, but there seem to be deeper problems
than the usual sorts of things. Add a comment in the makefile documenting
a case that fails on LP64 but not ILP32. PKGREVISION++.

- needs unistd.h
- use matching types with printf and scanf
- don't use gets
- fix bug caught by gcc -Wuninitialized
