Target std=gnu++14 rather than std=c++14 on Windows systems

[visceralfield]

The spirv_cross build.rs sets the c++ compiler to use the c++14 standard. On POSIX systems this is fine, because those systems will simply implicitly include the POSIX standard as well. This is not the case on Windows while using GCC, however - it uses the strict c++14 standard. This does not include some key functions used by spirv_cross, namely strdup. Attempting to build a crate with spirv-cross as a dependency on x64 Windows 10 with GCC 9.10 results in the following laundry list of errors:

error: failed to run custom build command for `spirv_cross v0.14.2`

I do not have time at the moment to test, but I believe this can be fixed by telling the compiler to use std=gnu++11. This will include the relevant POSIX standard headers to enable strdup and friends to compile correctly. I will test this when I have time and respond back in this issue if I test a solution that works.

Thanks for reporting the issue!

We do run CI against both x86_64-pc-windows-gnu and x86_64-pc-windows-msvc on Windows (https://github.com/grovesNL/spirv_cross/blob/master/appveyor.yml#L8) so we should be sure any fix passes on both environments.

Additionally - I can build this successfully with my mingw_w64 install at home, it's only with my MSYS2 based setup on another PC that I run into this issue. I believe mingw_w64 acts more POSIX-ey, but I'm not sure of the exact issue here.

[SonicZentropy]

Anybody have any more info on this? Running into it myself now

Still have this bug under Cygwin.
Can confirm that it works with mingw_w64 (g++ (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0)

[grovesNL]

If possible I'd recommend using MSVC for spirv_cross on Windows for now. I've hit some more issues with MSYS2/MinGW/Cygwin recently which sometimes need workarounds like rust-lang/rust#47048 (comment)
