bde has an implementation of clog[fl]. He may someday
commit it. I don't know if anyone ever worked on cpow[fl].
I stopped working on powl and tgammal when I returned my
commit bit due to differences with "higher-ranking" committers.

How have you tested the NetBSD and/or OpenBSD code? What is the
quality? Have the long double clogl and cpowl been tested on both
ld80 and ld128 hardware? See FreeBSD's lib/msun/src/math_private.h
for a discussion of possible issues of using I from complex.h in this

Well, of course, the various libm's look alike. They all started
life from Sun Microsystems fdlibm code. You can get the last
release from Netlib.
