    To determine if a compiler is Standard C, the existence and value (should
be 1 in standard C) of __STDC__ should be checked.

        You may also want to employ the "#error" preprocessor directive to yell
at you if the configuration of compiler-supplied macros, values, etc. is such
that your program will not run and/or compile correctly without modification.
