I think this is really a FreeBSD support question. In 2011, an OS really

Hmm, on FreeBSD I really have no other piece of software which complains
about lack of C99.
FreeBSD is planning on switching to a different compiler, llvm/clang,
and so the version of gcc is stale, but still it should be more than
sufficient to support C99. FreeBSD started a C99 effort a decade ago
and I haven't heard from this initiative in a long time as I thought
it was completed.

Hmm, the line
Implement new functions that appear in <complex.h>.
is marked as 1/2 done, 2008.
There is I believe experimental support for llvm/clang built into
FreeBSD 9, so you could try compiling with that instead of gcc.
Ok, I understand. This seems consistent. I will try to contact FreeBSD
support about it. Please do not change back the behaviour for FreeBSD
(towards emulation code) until this is clarified.
Yes, please mail freebsd-standa...@google.com
I haven't looked at what autoconf is testing exactly but I suspect
simply another argument must be provided in the autoconf script to get
it to pull up the C99 math functions its looking for.
Maybe, but it is looking in complex.h, where the C99 standard says
these must be (unconditionally).
