Note that you will never see g77 with any gcc version >= 4 as it no
longer exists.  The new Fortran front end is gfortran, and g77 ceased to
exist as of the 3.x series.

That does seem a bit strange.  Are you using the modular source tarballs
by accident?  The source is available as both a monolithic tarball
(gcc-x.y.z.tar.bz2) and as modular components (gcc-core-x.y.z.tar.bz2,
gcc-g++-x.y.z.tar.bz2, gcc-fortran-x.y.z.tar.bz2, etc.)  The behavior
you are seeing looks like what would happen if you only extracted the
gcc-core package which contains only the C language compiler (and
apparently treelang as well.)  If you want more than just C you need to
either use the monolithic tarball or overlay the other desired languages
on top of the contents of gcc-core.
