If you want to use the GNU C (gcc) compiler to compile your code from
the command line (at your athena% prompt) just type:

	add gnu              (once only in each window per login session)
	gcc myprog.c            (every time you want to compile)

(If you are using Linux or NetBSD and don't have gcc installed locally,
use "add gnu" instead)  If you use Makefiles to compile your programs, 
then put the following line at the top of your Makefile:

	CC=gcc

If you have any problems with this compiler, send mail to "gnu" with a
description of your problem.  Do not send mail to "bugs"; this is not
officially supported software, although you are likely to get help with
your problem from those who maintain the "gnu" file system at Athena.

For information on gcc, see our "stock" answer on What C COMPILERS are
available. You may also type the following from your athena% prompt:

	add gnu
	man gcc

Finally, if you are familiar with the "info" system in emacs, there is
information on gcc available by entering info with the keystrokes

	C-h i

and then typing

	g(/mit/gnu/info/dir)Top

Be sure to first type (at the athena% prompt):

	attach gnu
