-*** AC_PROG_CC no longer tests for VLAs, or whether __STDC__ is defined.
-  This ports better to MSVC, which does not support variable length
-  arrays and does not define __STDC__.  Although C99 requires VLAs,
-  they are optional in C11 and later.  Programs can use AC_C_VARARRAYS
-  and __STDC_NO_VLA__ to use VLAs if available.
