libm: Fix log-related symbol aliases.

- Do the weak alias dance for log, log2, log10, log1p, and their
f/l variants.

(Not strictly necessary for log2 and log10 since nothing in the
math library itself uses them -- only a computer scientist would
use log2 and only an engineer would use log10 -- but let's just do
it the same for all our forestry.)

- Provide long double aliases on vax.

- Sprinkle RCS ids.

__STDC__ is always defined on NetBSD.

More trailing white space.

Add some braces to make egcs happy. (This code could kill me.)

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

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.
