No, I did not mean for the permissions to be gone. Something happened 
when I moved from XP or Vista maybe, I talked a little about it with 
Corinna about it in this thread (well, it's split into two threads since 
one reply broke the threading :)). Annoying problem, though!

Hmm, are you running gcc 4.4? Because I don't see that warning. It 
compiles and links without warning when I add "-Wl,--enable-auto-import" 
to LDFLAGS.

Yes, it does. :) But you knew that already since you have already 
replied? :) Or maybe something happened when you posted and one got 
delayed. Anyway, thanks for your help, Dave, and let me also thank you 
so much for your work on gcc! And there are alot more people deserving 
thanks as well on this list! It's been very exiciting following cygwin 
these past few months!
