So what?  :-)

My understanding of Han-Wen's report is that FreeBSD has `complex
double' but does not provide `clog ()' et al. as part of its libc.
Thus, checking for the presence of those functions may be necessary
_even if_ complex doubles are available.

C99 (Section 7) does not seem to say whether these functions have to be
in libc.

Thanks,
Ludovic.
