Installing and using GCC on Cygwin - "set the environment variable CC to a working compiler"

I'm in a C++ class and I need to compile my programs so that they will run on the school's Unix platform. The compiler at school is called xlC, but I couldn't find a download for that on the internet so I'm trying GCC instead. I downloaded and installed Cygwin (from cygwin.com) so that I could use Unix on my PC, and now I'm trying to set up/run GCC. I'm trying to follow the directions on http://gcc.gnu.org/install/configure.html. Here's what happens:

Chiara Whiting@Chiara /cygdrive/c/chiara
$ mkdir c:/chiara/cfiles

Chiara Whiting@Chiara /cygdrive/c/chiara
$ cd c:/chiara/cfiles

Chiara Whiting@Chiara /cygdrive/c/chiara/cfiles
$ c:/program%20files/gcc-3.3.3/configure
Configuring for a i686-pc-cygwin host.
*** This configuration is not supported in the following subdirectories:
     target-libffi target-boehm-gc target-zlib target-libjava
    (Any other directories should still work fine.)
Created "Makefile" in /cygdrive/c/chiara/cfiles using "mh-frag"
cc: not found
*** The command 'cc -o conftest -g   conftest.c' failed.
*** You must set the environment variable CC to a working compiler.


Multiple Google searches have helped very little. I think I need to find a precompiled binary of GCC, but I don't know where.

Here's my system info:
Dell Latitude D600
Windows XP
GCC 3.3.3
The cygwin and GCC-3.3.3 folders are located in C:\Program%20Files.

I know nothing about Unix, as you can probably tell. Please explain this to me using small words. :) Thanks!

P.S.
C:/Chiara/cfiles is the directory where I'd like to save the compiled C++ programs.

Hi cmw44,
You don't need to compile or setup anything on gcc with cygwin. Just pick the gcc packet of cygwin to install and that's it. Runs right out-of-the-box.

Be warned about compiling gcc yourself - I did this on a 8 CPU Sun Enterprise machine with parallel make and it took about 1 hour and more than 1GB of HD space.

Cheers!

Stefan

Edit the makefile to read

$CC=gcc

instead of

$CC=cc
