Just as the Microsoft compiler compiles "Microsoft C", and the pcc
derived compilers compile "PCC C".  I am unaware of any C compiler
which everyone will agree is the "One True C Compiler".

In fact, it could be argued that gcc will eclipse pcc as the de facto
standard C compiler as vendors abandon pcc due to poor performance, etc.

I haven't seen any "net programs" that really use the gcc extensions.
The only extension I use myself is the function inlining directive, but
I always disable it with a:

	#ifndef __GNUC__
	#define inline
	#endif

if I'm not compiling with gcc.

I use gcc on SCO Xenix/UNIX for the following reasons:

	* It generates correct code.

	* It understands ANSI C function prototypes.

Niether compiler from SCO meets both criteria.
