Short warning on current Cygwin

[Fred Kiefer]

I updated my Cygwin environment this week and now I am no longer able to 
compile GNUstep on my machine, which worked ok with the older Cygwin. 
One problem is caused by gjc 3.3.3, this module provides libffi. But 
with the newer release ffi.h now includes another header file and this 
was left out of the shipment. (Does anybody know how to reach a Cygwin 
package maintainer? Or how to privde bug reoports for packages?)

The other problem is even worse. The way we are generating the list of 
exported symbols is no longer working. nm wont return any class names 
anymore, so classes cannot be exported, which breaks shared libraries 
for GNUstep. This may require a switch to a different export mechanism 
for your symbols. As far as I remember there already where a few patches 
for this. What I don't know is, if they are specific to certain GCC 
versions or could be used a s a general replacement.

For now I would suggest that if your Cygwin environment is working, try 
not tu update the GCC packages.
