I agree this would fix the #309 problem. I doubt however
it is possible to extract 'char* abort_reason' from
a 'int stat'...

I think we need to introduce a new opaque datatype that is
to be returned by drmaa_wait(). The new datatype would have
to serve as a wrapper for stat, rusage and abort_reason and
drmaa_wif* functions would simply operate on the new data
type instead of 'stat'.
