Hi Arno,

I made the same exact change internally.  It built and the full testsuite was
run afterwards:


                === acats Summary ===
# of expected passes            2320
# of unexpected failures        0
Native configuration is x86_64-test-dragonfly4.3

                === g++ tests ===

Running target unix

                === gnat Summary ===

# of expected passes            2467
# of expected failures          21
# of unsupported tests          5
/build/home/marino-huge/gcc-test-area/build/gcc/gnatmake version 6.0.0 20151114
(experimental)

                === objc tests ===


I think it would be okay to just "blindly" make the same changes to DragonFly
that you do for FreeBSD in the future.  It will almost always be the correct
thing, and if it isn't I'll still catch it with regular build checks.

Thanks for the quick fix,
john
