Public bug reported:
Older clang versions compiled all code with gcc-compatible flags. In
wily, clang cannot find omp.h header, used in conjunction with -fopenmp.
This is unlike gcc, which accepts the code, which is IMO the correct
behavior. This misbehavior was reported in https://github.com/clang-
omp/clang/issues/58 which also contains a workaround.
