- knf
- use cpp -traditional, since the default has now changed. We want to allow
unmatched single quotes!
- use fparseln, instead of a fixed 2k buffer.
- make all locals static and move to the top. This is so we can eventually
make calendar understand languages other than us_en
- add braces and continue's to clarify things.
- replace gratuitous fprintf uses with warnx.
- replace vforks() with forks() since we tried to print errors with stdio.
- add more warnings so that we know how things fail.
XXX: Eventually we'll have to remove the cpp dependency, and we should:
- make it use m4 instead [bad, breaks compatibility]
or
- add a small cpp like parser for #include [bad, too much code]
