ah thanks - really useful info, I hadn't realised the copyright was not
assigned to the FSF.

sure I think it is looking sensible to stop using libpth.  gm2 only
needs the two basic primitives create a context and switch to a context
in any case.  Furthermore it only needs these if the user wants
coroutines.  For most Modula-2 programs it isn't required.
