Benoit,

Actually, I did...in a way.  It ended up with Hummingbird (the creators of
Exceed) doing some work for us.  They were very good about helping out as much
as they could.  Without any previous knowledge of Cygwin32, they were still
willing to put some of their engineers on the problem.  After a couple of
weeks of work, they came up with some compatible libXX.a files and a few new
"interface" dlls.  They sent the new files to me as a "Proof of Concept"
product, I installed them, and everything just worked...and very well!!!  All
warnings were gone and everything looked and worked as it was
expected....which did NOT happen with Lesstif (a free version of Motif).
Right now, we are stuck on legal stuff, but hopefully, if a lot of other
people show interest, we can get passed that.

What I would suggest is to send email to Norbert Bedoucha
(norbert.bedoucha@hcl.com) at Hummingbird.  He may be willing to send you a
"demo" version of what they sent me.   If nothing else, it will show that
there is other interest out there besides our company.  Let him know that you
are trying to link Cygwin32 based code with Exceed.  Hopefully he can help.
With enough interest, they may be willing to release a Beta/Test version or
something.  You never know....they were pretty good about helping me!!!

Good Luck,

PS Let me know what happens...or just post it on the Cygwin32 mailing
list....so EVERYONE can know the outcome.  : )
