3.0.1 is dated, at  least 2 years old.  Maybe there are already some 
changes in the repository?

I need a simple testcase ;)  We should track down where it fails and
where not, does it work with cygwin-1.5.17 or is it not depending on the
version of cygwin?  I have another problem which breaks C++ binaries
which work fine with 1.5.17 but not with 1.5.18, regardless on which
version of cygwin it was compiled, however it works well in any case
when using gcc-3.3.3.

I introduced versioned libraries with 3.4, maybe I should rebuild 3.3.3
with this flag on too?
