Compiling Sather with gcc 4.5.0 produces numerous warnings about qualified 
void returns:

hello.c:4: warning: function definition has qualified void return type

I suggest for now the following, which adds a new compiler file allowing 
things within the tree to be adjusted.  The new file might later be used 
to turn on warnings selectively.  Just now it adds a -w to CFLAGS in the 
generated C code:
