Hey Mathieu,

At home (in Cygwin 64), I have a patch for urcu 0.9.2 to fix compilation issues.
This patch is however unrelated to building shared libraries (.dll files) in Cygwin.

Here is a patch (inline and attached) to build shared libraries on Cygwin (the one that you
requested). This patch is based on userspace-rcu 613086f69b4c8e6cc1b73b4e93d6d0497825d1ee.

I tested it on Ubuntu 14.04 ("behavior on non-cygwin builds"), but not on Cygwin as I don't have a Cygwin system at work.

Commands used to test the patch:

git clone https://github.com/urcu/userspace-rcu.git
cd userspace-rcu/
patch -p1 < ~/patches/0001-Port-build-shared-libraries-in-Cygwin.patch 
./configure --prefix=$HOME/builds/userspace-rcu/613086f69b4c8e6cc1b73b4e93d6d0497825d1ee/`date -Iseconds`
make -j 4
cd tests/
make check
cd ..
make install

Output of the test:

./run.sh unit_tests
./test_uatomic ................... ok     
./test_urcu_multiflavor .......... ok   
./test_urcu_multiflavor_dynlink .. ok   
All tests successful.
Files=3, Tests=78,  0 wallclock secs ( 0.03 usr  0.00 sys +  0.03 cusr  0.01 csys =  0.07 CPU)
Result: PASS

So, the Result is PASS, which is good.

Tonight, I will combine my 2 patches (the one that enables shared libraries in Cygwin, and the one that fixes various compilation issues in Cygwin)
and send it to the mailing list for review (along with the output of unit tests in Cygwin).
