	(Assuming I am thinking about your max() and min() functions
correctly): Well, actually, it does. GCC has an even better implimentation
of these than vc++.  The >? and <? operators for Max and Min respectively.
ie:
	2 >? 4 = 4
	2 <? 4 = 2

	Be warned however, that these may only work in C++ (I'm not sure).
If you want it to be compatable w/ vc++, just add:

#ifdef __GNUC__
#define max(a, b) (a >? b)
#define min(a, b) (a <? b)
#endif

To the beginning of your code.  Than you can use the min() and max()
functions the same way in both compilers and gcc will be able to optimize
for it.

	This is, just as it says, a dangerous function.  All you have to
do is hit too many keys for the buffer given to gets() and BOOM!  It isn't
that you're not allowed to do it, gcc is just politely recomending that
you don't.
