GNU Pascal and gcc/f77_(re)

According to R. P. C. Rodgers, M.D.:

We are working on merging Pascal into the GCC main distribution line.
Once this is complete, you can install GNU Pascal together with GCC
typing a command like `make LANGUAGES="C Pascal"'.  Then all GNU Pascal
patches will already be in the GCC source; additional GNU f77 patches
should not spoil them, so it will probably work.

And in case the f77 team and others are working on similar projects, it can
become `make LANGUAGES="C C++ Objective-C Pascal Fortran Ada Basic Foo Bar"',
one day ... (-:

Recently, Nils Bokermann sent a diff to this list which contains the
necessary changes to `toplev.c'.  We will include it into the GPC 
supplementary distribution (i.e. FAQ, WWW home page etc.), soon.

Hope this helps,

Hello!

If trying to build the gpc-2.0 with the gcc-2.7.2.1 with the GNU Fortran
enabled, will not run. There are some problems with the file toplev.c. Here is
a simple diff, which worked at mine.
