[Haskell-cafe] Terminating GLUT/GLFW programs

[Peter Verswyvelen]

Hi,

I had a similar (unsolved) problem with GLUT but on my system (Windows 
XP + GHC 6.8.2)  GLFW works fine, exiting is no problem at all.

But when building GLFW, make sure that the GHC gcc-lib directory comes 
*before* the MinGW/Cygwin directory in your PATH environment variable, 
since when linking, the LD.EXE bundled with GHC *must* be used.

Cheers,
Peter
