I verified that current versions of GCC on FreeBSD 10.3 have
this on...

...I believe since FreeBSD 10 has better libc support for the long 
math functions, so our best course of action (apart from counting 
down those months that FreeBSD 9 still has) is seeing that we can 
finally update lang/gcc from GCC 4.8 to at least 4.9, if not later.
