The intel C compiler [defaults to `-std=gnu98`](https://software.intel.com/content/www/us/en/develop/documentation/cpp-compiler-developer-guide-and-reference/top/compiler-reference/compiler-options/compiler-option-details/language-options/std-qstd.html#std-qstd_GUID-338F4C2A-560C-4338-8ACF-C4B022A7C865), which apparently causes problems with recent cpython source. Judging by the existing code in `CMakeLists.txt` and [this issue on the core cpython repo](python/cpython#568), somewhere around cpy3.6 cpython moved on to C99. This PR ensures that if intel compilers are being used on cpy>=3.6 source, the `-std=C99` flag will be added

@certik It's been a while since I've had personal access to the intel compiler suite, so I have no actual way of testing this PR out myself. However, I'm pretty sure it will solve your problem? Can you please try it out and let us know? |

Thanks, I'll give it a shot soon! |
