to be honest i haven't really found a way to fix this :-(
(short of switching to 64bit for both Pd and Gem)

there's some compatibility problem between the Pd-32bit build and the
Gem-32bit build for Windows.


both ship a "libwinpthread-1.dll", but unfortunately they are incompatible.

keep the original version around, in case things go havoc.
