Thanks.  The libf2c stuff looks quite reasonable.  Presumably you
found the missing pieces to fix these two problems you mentioned
(you may have mailed me about this before, but I can't find the
message):

*) make clean doesn't nuke the s-lib* files in the multilib directories.
*) libE77 is different than everything else.   The directory is removed 
   during a  make clean (as are the other lib?77 mutants) but the s-libe77
   file remains and that seems to be enough to make a subsequent build fail
   becuase there are no objects build.   Manually removing this file makes
   it work.
