C Library is GCC 4.7. Older GCC versions, and non-GNU compilers, can
still be used to compile programs using the GNU C Library.
+* Vector math library can be used with GCC 6.* w/o OpenMP SIMD constructs.
+ -ftree-loop-vectorize needed instead of -fopenmp in this case (visit
+ <https://sourceware.org/glibc/wiki/libmvec> for detailed information).

Security related changes:
* The nan, nanf and nanl functions no longer have unbounded stack usage
