how-to, GCC installation

[JF MARQUET (Y)]

Thanks a lot , or more !
This is etremely useful, and very rapid information (although we are on 
Sunday !).
You asked me what I felt as misleading in the documentation ; for 
beginners like me (google says I am not the only one...), it is hard to 
imagine that the "prerequisites" be really meaning that you cannot 
install GCC if it is not....already installed or almost (!), without 
saying many words (without saying any ?) on what you should do if it is 
not the case (which may represent 99 % of people trying to install GCC 
out of any "good LINUX distribution"?). I must confess that I 
misunderstood what "cross-compiler" meant (I thought of something going 
from one language to another...) ; now that I have quickly browsed on 
the term "cross compiler", and with your precious info, I am sure to 
succeed, some way or another (may be I will "cross compile" directly the 
program for which I was trynig to install GCC, which is...mutt !).
Thanks again.

JF MARQUET
