Note:  'getopt.c' is only required to build giftrans on DOS or OS/2 systems.
You can safely ignore it on Unix systems.

To compile giftrans on a Unix system:
   cc giftrans.c -o giftrans

You'll probably also want to copy the man page 'giftrans.1' to the directory
'/usr/local/man/man1' or some other appropriate place.
