directive is implementation-defined. The GNU C preprocessor recognizes
some pragmas, and passes unrecognized ones through to the preprocessor
-output, so they are available to the compilation pass. GNU C preprocessor

-compatibility previously supported pragmas are also recognized without
-the @samp{GCC}, however that use is deprecated.
