What I find odd is that IDL just crashes rather than give me a message
saying something about a missing symbol or the like. That's really
what I was expecting.

Compiling with MinGW or Visual Studio will be (I believe) a lot more work
since I have to remove the unixisms from my code which is not insignificant;
however, most of this has to do with signals, forks, and spawning. Cygwin
seems to have solved most of these porting issues which is why it would
be nice if that part worked.

I may try the above faq method; however, I have to do it for all my DLLs
and there are seven I use before I get to my DLM. That might also be a
lot of work.

Ok, thanks to all who have replied. I believe I got the answer I needed in
that "using a Cygwin compiled DLL is impossible with IDL". If I make some
progress on this in the form of a generic way to solve this problem, I'll
post back. If I just try ifdef'ing out my unix'y code, that might be
easier...

Thanks again!
