gcc --version shows egcs-2.91.66
I'm not sure of the difference between the two (gcc and egcs). I started reading
something about it yesterday. I think egcs was being merged with gcc??

Ok. This is way above my head. I am in beginner C++. I'm kinda following. But not
sure what the header is. I'm thinking that it's everything before the main()
function??

What is the purpose of -Wall??? Does this mean that there is no margin for error
in compiling the code??? Like, if it doesn't know exactly what is intended the it
won't continue.
Thanks,
