Question about egcs building w/native compiler

[nnorwitz@arinc.com]

     Hello!
     
     I'm trying to build the egcs compiler with the native cc (xlc) 
     compiler on an IBM AIX 4.2 box.
     
     I did a plain ./configure, then built with make bootstrap.
     It gets pretty far (builds stage1, but can't build stage2), but 
     eventually (in stage2) still tries to compile the fortran src.
     
     I don't have gcc on the machine and would like to build only the egcs 
     compiler (I'd rather try egcs than gcc, since I will probably only do 
     one).
     
     I had another problem which I solved.  xlc needs an -ma flag to handle 
     alloca() properly.  It would also work with a #pragma in the code, but 
     that's a pain.  After adding the -ma flag it worked fine.  That should 
     probably go in the configuration setup.
     
     Is there an easy way to get around the fortran problem?
     
     Thanks,
     Neal
