6644bf3e9b Undo the the changes in the previous revision (MANSRC now works right again).
Use ${INSTALL} instead of install.

5308354b7e Fixed use of too many args for `.Em'.
Fixed description of domain of y*().
Fixed description of error domain.  (This description is still half
redundant and half wrong, as in many other math man pages.  fdlibm
doesn't support the VAX or Tahoe.)
Fixed capitalization of `Bessel'.

973f098aab Compress manual pages (if desired) in the obj directory rather
than in the installation destination.  Should make release-building
substantially faster.  The msun Makefile changes simple adapt to the new
scheme.

Second part of update to fdlibm 5.2: speed up argument reduction for trig
functions in the case pi/4 < |x| < 3pi/4.

Remove unused static constants ("one").

First part of update to fdlibm 5.2: fix jn(n, x) and jnf(n, x).
jn(-1, x) was too large by a factor of 3.

e2014c1dcb Latest fix from jtc:
The fyl2xp1 instruction has such a limited range:
   -(1 - (sqrt(2) / 2)) <= x <= sqrt(2) - 1
it's not worth trying to 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).

3a8617a83f J.T. Conklin's latest version of the Sun math library.
-- Begin comments from J.T. Conklin:
The most significant improvement is the addition of "float" versions
of the math functions that take float arguments, return floats, and do
all operations in floating point.  This doesn't help (performance)
much on the i386, but they are still nice to have.

The float versions were orginally done by Cygnus' Ian Taylor when
fdlibm was integrated into the libm we support for embedded systems.
I gave Ian a copy of my libm as a starting point since I had already
fixed a lot of bugs & problems in Sun's original code.  After he was
done, I cleaned it up a bit and integrated the changes back into my
libm.
