building apple-gcc42 fails: C compiler cannot create executables.

[Timothy Goins]

I encountered this problem compiling 4.3.  In /usr/bin I had the gcc  
executable but no gcc-4.0 file, so I created a link (sudo ln -s /usr/ 
bin/gcc /usr/bin/gcc-4.0).  The -s is unnecessary, I believe, but I  
did it because my symbolic links show up in a different color.

What I don't know why the configuration looks for gcc-4.0(.1) and not  
just /usr/bin/gcc.  Seems to me the link ought be the current  
executable linked to a /usr/bin/gcc pointer.  That way the current  
gcc, like /opt/local/bin/gcc-4.3 on my system, could be located  
anywhere.

Am I missing something here?
