I've checked in the first installment of my planned reorganization of 
the invoke.texi chapter.  Here I've deleted the section placed randomly 
in the middle of option descriptions that contained only a paragraph 
about the name of the gcc executable, and incorporated that information 
into the chapter introduction instead.  I did a little bit of editing of 
the text in the introduction as well, and rewrote the one reference to 
the deleted node so it makes sense without it.
