...so I got the source from a bit of vestigial PGP code, removed "pgp_" from the name of getopt.c's only function and it compiled with no problems.

If you can't be bothered compiling it yourself, and you trust me not to freak with your digests, you can use this one. You'll probably need to set the filetype to &FF8 after gunzipping it.

I believe the PGP licence allows binary distribution. If I've misread it let me know and I'll take this down.
