Ah yes, that make sense.  Thanks also to avih for the reproducer receipt 
on linux, I can investigate now.

I'm fine either way, I've started on the unification of the symtabs 
already, but will fix the .def file thingy separate from that.

My secret hope was for a christmas present (aka release) ;-)  That still 
doesn't imply any hurry yet, but would be really nice.

Hmm, let's see ... I'm fairly sure to have the .def file problem fixed 
later today.  The symtab unification I don't know yet, perhaps end of the 
weekend or next week.  Basically I don't want the unification to delay a 
release until next year, if it would have otherwise happened this year. 
I don't know your end of year planning of course, if this weekend was your 
only time slot to do a release this year I would feel bad about being the 
reason for a delay until next year.  If we only talk about a delay of one 
to three weeks I'll be happy about waiting for the unification.

Anyway, waiting on the .def bug now :)


Ciao,
Michael.
