| # |
| # Newer versions of compilers might default to supporting C99, but older |
| # versions may require a special flag. |

| # Prior to CMake 3.1, setting CMAKE_C_STANDARD will not have any effect, |
| # so, unless and until we require CMake 3.1 or later, we have to do it |
| # ourselves on pre-3.1 CMake, so we just do it ourselves on all versions |
| # of CMake. |
| # |
| # Note: with CMake 3.1 through 3.5, the only compilers for which CMake |
| # handles CMAKE_C_STANDARD are GCC and Clang. 3.6 adds support only |
| # for Intel C; 3.9 adds support for PGI C, Sun C, and IBM XL C, and |
| # 3.10 adds support for Cray C and IAR C, but no version of CMake has |
| # support for HP C. Therefore, even if we use CMAKE_C_STANDARD with |
| # compilers for which CMake supports it, we may still have to do it |
| # ourselves on other compilers. |
