@ -1092,6 +1093,11 @@ Some Windows headers define min and max as macros which may cause compatibility
It is highly recommended to [define NOMINMAX](http://stackoverflow.com/questions/4913922/possible-problems-with-nominmax-on-visual-c) before including Windows headers to workaround this issue.
To workaround the incompatibility with these macros, GLM will systematically undef these macros if they are defined.
### <a name="section7_13"></a> 7.13. Constant expressions support
GLM has some C++ <a href="http://en.cppreference.com/w/cpp/language/constexpr">constant expressions</a> support. However, GLM automatically detects the use of SIMD instruction sets through compiler arguments to populate its implementation with SIMD intrinsics.
Unfortunately, GCC and Clang doesn't support SIMD instrinsics as constant expressions. To allow constant expressions on all vectors and matrices types, define GLM\_FORCE\_PURE before including GLM headers.
