This was done for C++ by commit v3.5.0-rc1~69^2 (Record compile features for MinGW Clang on Windows, 2016-01-11). Make the same change for C. The `UNIX` condition on Clang C compiler features was already dropped by refactoring in commit v3.9.0-rc1~17^2~4 (Compilers: Port to use default cmake_record_lang_compile_features macros, 2017-05-10). Our documentation already claims support for this combination. This was simply an oversight when support was added for MinGW Clang C++. Issue: #15897 Issue: #15943
