fix so that it doesn't interact strangely with ARCH_SRCS definitions
in the base Makefile, makes the lib built correctly again for eg amd64
(seen by wiz)

branches: 1.1.2;
Add manpages for the complex math functions, originally from SUSv3,
roff source from the Linux documentation project.
Modifications before import:
-added NetBSD RCS ID
-removed Linux PROLOG and declarations with "long double"
-ran the "deshallify" script as required by The Open Group
Split out complex related things into an own Makefile fragment.
Thanks to hubertf for directions.

Add C99 complex support, for double and float.
Most complex function implementations are from the "c9x-complex" library,
originating from the "cephes" math library, see
http://www.netlib.org/cephes/, from Stephen L. Moshier, incorporated and
redistributed with the NetBSD license by permission of the author.

Error behaviour and other boundary conditions (branch cuts)
need to be looked at.

For namespace sanity, I've done the rename/weak alias procedure to
most of the exported functions which are also used internally.
Didn't do so for sin/cos(f) yet because assembler implementations use
them directly, and renaming functions shared between the main libm
and the machine specific "overlay" might raise binary compatibility
issues.

As noticed by Stathis Kamperis, the original implementation does not
always return the correct principal value (with real>=0).
(eg cacosh(ccos(1.0I)) was -1)
Replace by a more ground-up one which should do better.

For namespace sanity, I've done the rename/weak alias procedure to
most of the exported functions which are also used internally.
Didn't do so for sin/cos(f) yet because assembler implementations use
them directly, and renaming functions shared between the main libm

Add C99 complex support, for double and float.

compare to zero, instead of using signbit, and be more specific in comment.
-0.0 > 0 is also false. no functional change.

while this is mostly a change to be consistent in style (the rest of the
comparisons aren't done with signbit), it is also a micro-optimization.

with our default compile flags, calls to copysign are libm calls (and a
whole function call!!). this generates more efficient code.

csqrt has a branch cut on the negative real axis, and this requires
delicacy in order to maintain continuity around it.

we have an initial case to deal with a fairly common case: getting
a real number. Avoid dealing with the branch cut in this case by
checking if the real part is negative.

later, -0.0 < 0 is not met, so instead, test for a negative number
using signbit, so negative zero is also treated as a negative number.

Fixes last part of PR lib/51427: libm issues triggered by py-numpy

ok riastradh

Spare ourselves a fabs call. We already check the sign later.
w = r + y*I is the same as w = r because this is the y == 0 case.

no functional change.
