You have quite enough on your plate to be responding to every message; 
particularly on a bit of a minority interest like Cygwin support.

As I said, the result is "quirky" and so not at all satisfactory, in any 
case.  I agree with you; prticularly in light of various other Cygwin 
troubles that come to light  in trying to support gfortran on that platform.

I will endeavour to find out who can help.  This is not at all evident since 
many, if not most, of the gcc developers seem to be somewhat in awe of the 
innards of error handling.  I'll come back to you on it.

PS Have been keeping an eye on octave developments - well done on 
octave-2.9.
