Yeap.

More or less.

Not always, but most of the time.

The crash is in the entry point I guess.

Yes it supports stabs.

I never tried.

I guess you mean link when you say rebuild, no? Well that's one solution. The 
other, heavilly used by Robert and me, is just compress the file with djp. DJP 
will remove the stabs debug info without any problem.

Now for Tomas:
Did you ported the GPIB thing from the LLP? If yes, can you point me to some 
test (step by step) to make it work? In some weeks I'll need to control a 
scanner (for meassurements, not to scan peactures) and the idiots of NI only 
provided MSC .obj files for the board (GPIB-PCII/IIA) and I really hate the 
idea to make the program with Quick C (I prefer to hack the original driver if 
needed ;-).
