"tools" meaning things like autoconf, automake, libtool...?  Most of
these tools are scripts -- never touched by gcc at all.  Only the
interpreters (perl, m4, and sh) are compiled, and their behavior should 
be constant no matter what compiler you use. :)  (Indeed, the behavior 
of automake & libtool is supposed to be the same no matter what 
*interpreter* you use.)
