What happen if... (related GPL & src)

[hgbasm <hgbasm at yahoo dot com dot mx>]

I have a question.

I will read or desire to read the source code of gcc, but if I for 
example make some anotations or some work based in my notes, or I get a 
idea of how to implement X thing,  or I think that certain idea is nice, 
and then I make my own compiler this compiler should need by under GPL?

Altought I consider a little opaque the concept of the "programm" in 
that licence, but anyway, I like that you answer first this question.



Hope you can help me out.
