Fixing Win32 build with SCons

[mak77]

don't remember if this has already been fixed but stdout.txt and stderr.txt should not be written to game dir, but they should be written to user dir, in Vista the program cannot write to its folder

i don't know what other problems are related to windows, what are related to incomplete data, what to normale development... i get frequent crashes but different results selecting different tracks or cars

however i compile on XP, on Vista i have only tested the game

latest build does not compile because it lacks SDL into libs

else:
libs_link = [ 'opengl32', 'glu32', 'glew32', 'mingw32', 'SDLmain', 'SDL', common_libs ]

I could also suggest to compress (don't know if scons can call external tools) the executable using UPX, the final exe is now 31MB while compressed it's about 4.5MB

also "Status: Using GLEW 1.4.0" is probably lacking a \n
