Hi Charles,

ops I missed the iso libraries at the end:

so:

gm2 -g -flibs=pim-coroutine,pim,iso -c testexecutive.mod
gm2 -g -flibs=pim-coroutine,pim,iso testexecutive.mod -lpth

should hopefully work (for 4.1.2 gm2, maybe 4.7.3 as well - although I'm
currently seeing 32bit/64bit confusion in some of the 4.7.3 libraries -
which is being worked on at present).  The -lpth is required for the
context switch primitives.

regards,
Gaius
