WHY ?

If your C-compiler (or someone else's) have the feature to make these non-standard
features - DON'T USE THEM - DON'T RELY ON THEM....

If you use all these nasty little undocumented features a specific programming
language, operating system, ...etc... has you're getting yourself into troubles!

	1) Your code will be hard to understand by others (and yourself after
	   some time)
	2) Your code is NON-STANDARD!!!
	3) Your code will be non-portable between machines/compilers.
	4) The next release of the compiler have no obligation to follow
	   previous non-documented features. So your fine 10,000 lines
	   program will not compile (in best case, worst case it will compile
	   but yields unpredictable results).

SO - stick to the standard and what is approved to be portable/documented.
