What OS are you working on? That may tell you what native C compiler you've used. Also, check the output for 'ls -l `which cc`'. (Note the backquotes around 'which'). You may find that cc is actually a link to gcc (quite common). As for the documentation, is it for learning C or learning how to use cc/gcc? For C and debugging links, check the
Unix Tutorials/Programming Tutorials/Shell Scripting Tutorials page.
In fact, I think that should answer almost all your questions. And one more piece of advice... check the FAQs page. You will get tutorials, recommended pages, ready-made scripts and more.

LEARN ABOUT DEBIAN
builder-cc
BUILDER-CC(1) Debian GNU/Linux BUILDER-CC(1)
NAME
builder-cc - gcc wrapper to facilitate pentium-optimizations
SYNOPSIS
export DEBIAN_BUILDARCH=architecture
export DEBIAN_BUILDGCCVER=gcc-version
gcc ...
DESCRIPTION
The builder-cc wrapper is normally used by calling gcc as usual. If the environment variable DEBIAN_BUILDARCH is not set, builder-cc does
nothing, and the real gcc is invoked with the specified arguments.
When the DEBIAN_BUILDARCH environment variable is set, builder-cc invokes gcc with the specified arguments, plus -mcpu=DEBIAN_BUILDARCH
-march=DEBIAN_BUILDARCH This has the effect of telling gcc to use architecture-specific optimizations without changing the command line.
This is particularly useful for package builds.
If DEBIAN_BUILDGCCVER is not set, builder-cc calls gcc.real. If DEBIAN_BUILDGCCVER is set, builder-cc calls gcc-DEBIAN_BUILDGCCVER
instead.
ENVIRONMENT
DEBIAN_BUILDARCH
If set, the architecture to compile for. Useful values are pentium or pentiumpro.
DEBIAN_BUILDGCCVER
If set, the version of gcc to be invoked. Useful values are 3.0 or 2.95.
NOTES
The real gcc is renamed gcc.real, and a diversion is registered with dpkg-divert(1). Thus builder-cc's idea of the default gcc is dictated
by whatever package installed /usr/bin/gcc.
