General information:

    ftp://kampi.hut.fi/jtv/gnu-pascal/
    http://agnes.dida.physik.uni-essen.de/~gnu-pascal/

The best documentation available at the moment is the
Info documentation included in the 2.7.2-pre-release.
The mentioned problem is described in the "Borland Pascal" 
section.

You can also contact the GNU Pascal mailing list, gpc AT hut DOT fi.
To subscribe, write to gpc-request AT hut DOT fi.

In short: Compile a unit with

    gpc -c myunit.pas

link it with

    gpc myprog.pas myunit.o -o myprog

In 2.6.3, you must include (somehow) the Interface in the
source of the program.  The easiest way to do this is to
(*$include *) the *whole* :-( Unit into the program:

    (*$I MyUnit *)

    Program MyProg;

    uses
      MyUnit;

    begin
      [...]
    end.

This is not necessary in 2.7.2, and there is also an --automake
option for automatic compilation and linking of Units.  
See the 2.7.2 doc for details.
