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.

Assembly language versions of some of the "float" functions.

1af6796a8d
The fyl2xp1 instruction has a limited range:
...
-(1 - (sqrt(2) / 2)) <= x <= sqrt(2) - 1
so we can't use it.
Also, I'm not sure fyl2xp1's extra precision will
matter once the result is converted from extended
real (80 bits) back to double real (64 bits).

Use BYTE_ORDER == LITTLE_ENDIAN instead of -Dnational to select byte order
...
of floating point numbers.
The assumption that a processor's floats use the same order as its integers
is probably unwarranted, but it is better than requiring non-national CPUs
to #define national, as that drags in national-specific code too.
(According to a comment in the code, the national FPU does not do infinity)
