similar to this issue #524

Since 2016, GLM has been modified such that anonymous struct checks against GCC -Wpedantic cause warnings again. This appears to be because glm/detail/type_vec2.hpp, glm/detail/type_vec3.hpp and glm/detail/type_vec4.hpp have actually removed the fix seen already in use here

error example:

.../glm/detail/type_vec4.hpp:34:28: error: ISO C++ prohibits anonymous structs [-Werror=pedantic]
     struct { T s, t, p, q; };
                            ^

Last time the following lines were used to simply suppress compiler warnings at critical sites, like so:

#if GLM_COMPILER & GLM_COMPILER_GCC
#				pragma GCC diagnostic push
#				pragma GCC diagnostic ignored "-Wpedantic"
#			endif
#			if GLM_COMPILER & GLM_COMPILER_CLANG
#				pragma clang diagnostic push
#				pragma clang diagnostic ignored "-Wgnu-anonymous-struct"
#				pragma clang diagnostic ignored "-Wnested-anon-types"
#			endif

 ... // anonymous struct code

#			if GLM_COMPILER & GLM_COMPILER_CLANG
#				pragma clang diagnostic pop
#			endif
#			if GLM_COMPILER & GLM_COMPILER_GCC
#				pragma GCC diagnostic pop
#			endif

Is there a reason why this has since been removed as of the latest development branch (as far as I can tell)? There doesn't appear to be a way to simply mute anonymous struct warnings in GCC and pedantic is required for my code base.

I'm able to make the changes locally with no pedantic errors, but I believe this issue has actually regressed into all places where it was previously needed (quaternion and vec1 need this as well?)
