I understand all this, but this case seems an odd one to me. If I am
missing a library I expect to find a clear error message that it needs
it, but here I just got nothing. I agree that this not a cygwin problem.
I have yet to update my old gfortran 4.2. on linux to 4.3 and I guess 
I will have the same problem as the linux needs upgrading too. I'll know 
what to expect than.

I really didn't foresee the Internet. But then, neither did the computer 
industry. Not that that tells us very much, of course - the computer 
industry didn't even foresee that the century  was going to end.
