I asked Roland to commit it if it fixes problems for current users.  I 
am planning on rewriting the compiler & wrapper stuff next week, and it 
will all very likely change anyway.

However, I'm of two minds on the way that the wrapper framework should 
work.  I would very much like for packages to understand the different 
compilers that can be used, but I'm slowly coming to the conclusion that 
we should have the wrapper framework just make other compilers look like 
GCC.  I haven't come across configure scripts that assume "gcc" is the 
GNU compiler because autoconf provides its own macros for compiler 
detection that check for GNU gcc in the right way.  However, the answer 
to the question of whether the gcc alias should be created can be 
deferred till later as the rewrite will make it easy to go one way or 
the other (I favor letting experimenting with both options to see which 
way is best).
