c271d4f25f Fix merge error: drop machine from an older workaround for machine.sse 
under compat32, drop the assertion, initialize oldlen.

7f1183f226 Add support for fenv.h interface for i386 and amd64. 
Submitted by Stathis Kamperis as part of GSoC 2010 and ported from
FreeBSD.

d4def06880 -build ldexp/frexp/modf locally again rather than relying on libc 
reaching over, to get things into a sane state,
-do the usual namespace protection game with scalbn(f) because it
 is used internally
(more symbol renamings are necessary)

The weak_alias change for mc68881 is untested.

d5a3d97bc4 build s_frexp.c, s_ldexp.c and s_modf.c here for new platforms, since they 
don't exist as compat functions in libc.

current list of new platforms: powerpc64.

from dennis.c.ferguson@gmail.com in PR#43042.  idea to not put compat
functions into new platforms from drochner@netbsd.

f12889bbfb fix return value in case of NaN input 
(the code also shortcuts the +-inf case, but this was OK before -- it
only avoids an extra check of the mantissa)

aa89e1b426 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.

fddc3457b2 Change the use of formally undocumented features, which have now been 
made to fail.  Specifically, change
.ifdef(SYMBOL) -> .ifdef SYMBOL or .if defined(SYMBOL),
and corresponding for .ifndef.

Also correct one error in lib/libm/Makefile (.ifdef (${MKCOMPLEX} != "no")?!?).

39ba286079 as in exp(), treat +/-Inf and NaN arguments specially, should fix 
eg expf(-Inf) which was Nan previously
(We could avoid touching the i387 on amd64 in these cases, but we'd
need to bypass the ABI abstraction macros, so leave it the old way
for now.)

bc43bac5ca -fix an obvious mistake in fpcw check 
-replace ARG_DOUBLE_ONE_HALF by _MSW/_LSW because this reflects the
 intention and also matches the terms used in C code,
 also make the code where the fpcw overwrites the argument a bit
 self-documenting
 (this abstraction sucks because it forces to write inefficient code)

138486a3df According to C99: 
6.11.5  Storage-class specifiers

       [#1] The placement of a storage-class specifier  other  than
       at   the  beginning  of  the  declaration  specifiers  in  a
       declaration is an obsolescent feature.

and gcc -Wextra warns about this, so s/const static/static const/

c7a43da627 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.
