Environment variables/cc missing

[Stephen Schroder]

In order to install my soundcard driver, cc, gcc, and
cl need to be found when I execute ./configure.  When
./configure fails to run, the report is that none of
the three can be found.  Special emphasis, for some
reason, is given on the fact that cc can not be found
in $PATH.  While cc can't be found anywhere on my hard
drive, both gcc and cl do exist.

Why doesn't cc exist, and where can I get it?  Where
are the system environment variables located, so I can
make gcc and cl findable by adding their directories
to the $PATH statement?

Thanks,
Steve
