libm: Make s_nexttowardf.c work when long double is double.
Seems likely that there are other parts of libm which would benefit
from being defined unconditionally in terms of ieee_ext_u, with
ieee_ext_u as an alias for ieee_double_u, in this scenario.  But I
haven't gone looking yet.

libm: If long double is double, nexttowardl is nextafter.
long double nexttowardl(long double, long double);
double nextafter(double, double);

long double nexttowardl(long double, long double);
double nextafter(double, double);

libm: If long double is double, nexttowardl is nextafter.

long double nexttowardl(long double, long double);
double nextafter(double, double);

Also pull up rev 1.15 and 1.16 for ticket #217:

On systems without __HAVE_LONG_DOUBLE, alias nexttoward() to nextafter().

On second thought, don't introduce nexttowardl() since we don't have that
yet elsewhere.

On systems without __HAVE_LONG_DOUBLE, also alias nexttoward() and
nexttowardl() to nextafter().

Rebase to HEAD as of a few days ago.

sync with head.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Merge riastradh-drm2 to HEAD.

If __HAVE_LONG_DOUBLE is not defined,
add a strong alias for nextafterl to nextafter

according to C99/POSIX, nextafter(x,y) should return y if x==y, from
Henning Petersen per PR lib/44875

__STDC__ is always defined on NetBSD.

More trailing white space.

rcsid facism, WARNSify

Id -> NetBSD

LIBM_SCCS must be defined for the RCS ID to be defined.
This library will soon be used by DJGPP.  And since memory is often tight
on DOS machines, there is little benifit to be had from including RCS IDs.

Change int -> int32_t and unsigned int -> u_int32_t to improve portabilty
to machines where int != 32 bits.

Float versions of math functions.  From Ian Taylor (ian@cygnus.com), with
minor changes by me.

Don't determine byte order at run time.
This also "solves" the problem of GCC optimization leading to incorrect
results.

Add RCS ID's.

Include <math.h> instead of "fdlibm.h"
Byteorder fix for s_frexp.c.
