this is really strange. Seems to be a OpenGL thing, but i can not imagine
that why this change was done on windows OpenGL implementation.

Because gem moved to FTGL recently, the windows part has not been worked
on yet.

this is in gemlibs ? the particle library is now included in
gem/src/Particle. No need to compile that anymore.

I think pspray is a demo for partlib and has nothing to do with gem.
So you can ignore it.

On my system it says 2.5.
