Fix 1992/buzzard.2 alt code, add try scripts

The bug fix is simply so it can compile. It assumed exit(3) returned a
value, not void. The fixes noted in the remarks (though I did not see
them at a quick glance) of the author are not in the alt version (that's
the purpose of it).

The try.sh and try.alt.sh scripts correspond to the entry and the alt
code.

Updated .gitignore.

Added 'first.alt' to Makefile for the try.alt.sh script.
