This fix is perfect.

Note that it exploits the fact that on MirBSD, both __OpenBSD__ and
__MirBSD__ are defined [1].

gnulib is probably the second-best POSIX compliance test suite nowadays,
after the OpenGroup's testsuite.

Regarding use of openbsd* in *.m4 files: You might also want to look at
  c-stack.m4
  gc-random.m4
  host-os.m4
if you have access to such a machine.
