Hi Michael,

ah yes the gm2-13 now uses named paths (which is prefixed to the library
procedure).  How is SizesReal.mod compiled?  At a guess does it have an explicit
-Ipath/to/m2/m2iso?  If so then this would remove the named path.  If
the guess is wrong any chance you can post the command line used to
generate SizesReal.o

The following url is an example of creating a shared library with
gm2-13, which might be of use?
