OpenLibm has an implementation of fenv.h internally. This may be problematic in case you want it to build against the host system's implementation, as it would require you to somehow take the fenv.h file out of the compiler search path. Simply use a different naming scheme, similar to openlibm.h and openlibm_complex.h. If we want to build against the host's fenv.h, we can simply add an '#include <fenv.h>' from within this header.
