OK, but I think further rearrangement in feupdateenv will end up being 
needed to fix bug 16918 (libc_feupdateenv_vfp returns void and doesn't 
test whether exception traps were successfully enabled, so the approach in 
your implementation is not well-suited to handling the FE_NOMASK_ENV case 
properly, although it matches the buggy handling in the existing code).
