2b6ca0f6a5 Detach k_rem_pio2f.c from the build since it is now unused. It is a libm
internal so this shouldn't cause version problems.

32948b81c4 The logb() functions are not just ieee754 "test" functions, but are
standard in C99 and POSIX.1-2001+.  They are also not deprecated, since
apart from being standard they can handle special args slightly better
than the ilogb() functions.

Move their documentation to ilogb.3.  Try to use consistent and improved
wording for both sets of functions.  All of ieee854, C99 and POSIX
have better wording and more details for special args.

Add history for the logb() functions and ilogbl().  Fix history for
ilogb().

aeb5e711f3 - Remove s_ldexpf.c (now aliased to scalbn.)
- Add nexttoward{,f,l} and nextafterl.  On all platforms,
  nexttowardl is an alias for nextafterl.
- Add fmal.
- Add man pages for new routines: fmal, nextafterl,
  nexttoward{,f,l}, scalb{,l}nl.

Note that on platforms where long double is the same as double, we
generally just alias the double versions of the routines, since doing
so avoids extra work on the source code level and redundant code in
the binary.  In particular:

		ldbl53		ldbl64/113
fmal       	s_fma.c		s_fmal.c
ldexpl     	s_scalbn.c	s_scalbnl.c
nextafterl 	s_nextafter.c	s_nextafterl.c
nexttoward 	s_nextafter.c	s_nexttoward.c
nexttowardf	s_nexttowardf.c	s_nexttowardf.c
nexttowardl	s_nextafter.c	s_nextafterl.c

29bf6af890 - Move the functions presently described in in ieee(3) to their own
manpages.  They are not very related, so separating them makes it

2208ce0a06 Replace s_isnan.c and s_isnanf.c with the more compact s_isnan.c from
libc.  The externally-visible effect of this is to add __isnanl() to
libm, which means that libm.so.2 can once again link against libc.so.4
when LD_BIND_NOW is set.  This was broken by the addition of fdiml(),
which calls __isnanl().

ec79bc0da9 Fix two bugs in the signbit() macro, which was implemented last year:
- It was added to libc instead of libm.  Hopefully no programs rely
  on this mistake.

- It didn't work properly on large long doubles because its argument
  was converted to type double, resulting in undefined behavior.

240dbabfa8 Implement the classification macros isfinite(), isinf(), isnan(), and
isnormal() the hard way, rather than relying on fpclassify().  This is
a lose in the sense that we need a total of 12 functions, but it is
necessary for binary compatibility because we have never bumped libm's
major version number.  In particular, isinf(), isnan(), and isnanf()
were BSD libc functions before they were C99 macros, so we can't
reimplement them in terms of fpclassify() without adding a dependency
on libc.so.5.  I have tried to arrange things so that programs that
could be compiled in FreeBSD 4.X will generate the same external
references when compiled in 5.X.  At the same time, the new macros
should remain C99-compliant.

The isinf() and isnan() functions remain in libc for historical
reasons; however, I have moved the functions that implement the macros
isfinite() and isnormal() to libm where they belong.  Moreover,
half a dozen MD versions of isinf() and isnan() have been replaced
with MI versions that work equally well.

9428e108c9 Add C99's nearbyint{,f}() functions as wrappers around rint().
These trivial implementations are about 25 times slower than
rint{,f}() on x86 due to the FP environment save/restore.
They should eventually be redone in terms of fegetround() and
bit fiddling.

e334ea2edc - fabsl.c should be named s_fabsl.c for consistency with libmsun's
documented naming scheme (unfortunately the documentation isn't in the
   tree as far as I can tell); no repocopy is required as there is no
   history to preserve.

 - replace simple and almost-correct implementation with slightly hackish
   but definitely correct implementation (tested on i386, alpha, sparc64)
   which requires pulling in fpmath.h and the MD _fpmath.h from libc.

 - try not to make a mess of the Makefile in the process.

 - enterprising minds are encouraged to implement more C99 long double
   functions.

41d8423f71 Stage 3 of dynamic root support. Make all the libraries needed to run
binaries in /bin and /sbin installed in /lib. Only the versioned files
reside in /lib, the .so symlink continues to live /usr/lib so the
toolchain doesn't need to be modified.

3819e84017 Only provide one copy of the math functions. If we provide a MD function,
do not also provide a __generic_XXX version as well.  This is how we
used to runtime select the generic vs i387 versions on the i386 platform.

This saves a pile of #defines in the src/math_private.h file to undo the
__generic_XXX renames in some of the *.c files.

c3e6df78e1 Now that we do not need to do runtime detection for the broken default
fp emulator, stop doing the runtime selection of hardware or emulated
floating point operations on i386.  Note that I have not suppressed the
duplicate compiles yet.

While here, fix the alpha.  It has provided specific copysign/copysignf
functions since the beginning of time, but they have never been used.

c7b111cba8 Added new bsd.incs.mk which handles installing of header files
via INCS.  Implemented INCSLINKS (equivalent to SYMLINKS) to
handle symlinking include files.  Allow for multiple groups of
include files to be installed, with the powerful INCSGROUPS knob.
Documentation to follow.

Added standard `includes' and `incsinstall' targets, use them
in Makefile.inc1.  Headers from the following makefiles were
not installed before (during `includes' in Makefile.inc1):

	kerberos5/lib/libtelnet/Makefile
	lib/libbz2/Makefile
	lib/libdevinfo/Makefile
	lib/libform/Makefile
	lib/libisc/Makefile
	lib/libmenu/Makefile
	lib/libmilter/Makefile
	lib/libpanel/Makefile

Replaced all `beforeinstall' targets for installing includes
with the INCS stuff.

Renamed INCDIR to INCSDIR, for consistency with FILES and SCRIPTS,
and for compatibility with NetBSD.  Similarly for INCOWN, INCGRP,
and INCMODE.

Consistently use INCLUDEDIR instead of /usr/include.

gnu/lib/libstdc++/Makefile and gnu/lib/libsupc++/Makefile changes
were only lightly tested due to the missing contrib/libstdc++-v3.
I fully tested the pre-WIP_GCC31 version of this patch with the
contrib/libstdc++.295 stuff.

These changes have been tested on i386 with the -DNO_WERROR "make
world" and "make release".
