[R-pkg-devel] why doesn't CRAN add -fopenmp to SHLIB_OPENMP_CXXFLAGS for Mac OS?

For example, mvnfast CRAN binaries could take advantage of OpenMP.

The OpenMx team has been building Mac OS binaries with openmp enabled 
for years. We compile with gcc and bundle the necessary openmp enabled 
libraries with the binary. Why couldn't CRAN do this?
