I can now complete  a multilib build of the languages c, c++, objc and fortran
on a G4 under Darwin8 if I apply the following patch...

and do a...

 cd libgfortran
 aclocal -I  ../config
 autoconf -I ../config
 cd ..
 cd zlib
 aclocal -I  ../config
 autoreconf -I ../config
 cd ..

before I run configure. I have worked out a similar patch for configure.ac in
libjava which I will test next on a build with the java language included.
