It doesn't matter if I run java.exe from a cygwin windows (bash shell), a
dos box or directly fom eclipse. It's always the same.
On the one hand if the precompiled library works why not using it. On the
other hand I'd like to know why it doesn't work and if I one day want to
patch something I can only do it if I can build from source.
