Hi Gour,

the command line switches have changed a little - now gm2 uses libtool.
There are some examples in the gcc/gm2/examples/shared directory and a
pretty comprehensive example given in gcc/gm2/examples/pge.

Absolutely - I'm the the process of implementing pge using this
technique - and it works well.  swig is used to build the interface
bridge for (C++/m2) to Python and Modula-2 gives you the safely and
runtime checking etc.  Passing complex data structures bad and forth
needs a little thought but it can be done - passing fundamental data
types is close to trivial.  Also it might be worth checking
gcc/gm2/examples/swig
