opengl_tools/glm/test/core/core_func_integer.cpp:590:33: error: ‘_BitScanReverse’ was not declared in this scope
_BitScanReverse(&Result, Value);

opengl_tools/glm/test/core/core_func_integer.cpp:954:33: error: ‘_BitScanForward’ was not declared in this scope
_BitScanForward(&Result, Value);

_BitScanReverse and _BitScanForward is MSVC specific functions

This issue is now fixed in GLM 0.9.6 and master branches.

Thanks for reporting,
