constexpr tvec4<T, P>::tvec4

[ma30002000]

In GLM 0.9.8.1,

template
GLM_FUNC_QUALIFIER GLM_CONSTEXPR_SIMD tvec4::tvec4(A a, B b, C c, D d)

should rather be declared

template
GLM_FUNC_QUALIFIER GLM_CONSTEXPR tvec4::tvec4(A a, B b, C c, D d) :

since no SIMD implementation actually exists, allowing the ctor to be used in constexprs when GLM_ARCH != GLM_ARCH_PURE

I'm getting a very similar error with glm-0.9.8.1 as well as the latest master branch, however, only when GLM_FORCE_UNRESTRICTED_GENTYPE is defined:

Severity    Code    Description Project File    Line    Suppression State
Error   C2475   'glm::tvec4<float,glm::aligned_lowp>::tvec4': redefinition; 'constexpr' specifier mismatch  glm-0.9.8.1\glm\detail\type_vec4_simd.inl   344 
Error   C2475   'glm::tvec4<float,glm::aligned_mediump>::tvec4': redefinition; 'constexpr' specifier mismatch   glm-0.9.8.1\glm\detail\type_vec4_simd.inl   351 
Error   C2475   'glm::tvec4<float,3>::tvec4': redefinition; 'constexpr' specifier mismatch  glm-0.9.8.1\glm\detail\type_vec4_simd.inl   358 

These are the lines:
GLM_FUNC_QUALIFIER GLM_CONSTEXPR_CTOR tvec4<float, aligned_lowp>::tvec4()
GLM_FUNC_QUALIFIER GLM_CONSTEXPR_CTOR tvec4<float, aligned_mediump>::tvec4()
GLM_FUNC_QUALIFIER GLM_CONSTEXPR_CTOR tvec4<float, aligned_highp>::tvec4()

I wonder why it's parsing type_vec4_simd.inl at all, I'm using the default flags/defines, no SSE or anything.

Possibly related: #555. I'm on VS2015U3 as well.

This issue should be fixed in GLM 0.9.8 and master branches.

Thanks for reporting,
