gcc 5.0 has a more than 50% implementation of -fcilkplus.  It's probably
a chicken-and-egg question whether this gcc implementation will become
somewhat useful, and whether the implied vectorization pragmas will
become available for plain C99.  Even if these did happen, I suppose the
other response about slim chance of C or C++ standardization would be
accurate.
