Fix remainder() and remainderf() in round-towards-minus-infinity mode when the result is +-0. IEEE754 requires (in all rounding modes) that if the result is +-0 then its sign is the same as that of the first arg, but in round-towards-minus-infinity mode an uncorrected implementation detail always reversed the sign. (The detail is that x-x with x's sign positive gives -0 in this mode only, but the algorithm assumed that x-x always has positive sign for such x.)
remquo() and remquof() seem to need the same fix, but I cannot test them yet.
Use long doubles when mixing NaN args. This trick improves consistency of results on at least amd64, so that more serious problems like the above aren't hidden in simple regression tests by noise for the NaNs. On amd64, hardware remainder should be used since it is about 10 times faster than software remainder and is already used for remquo(), but it involves using the i387 even for floats and doubles, and the i387 does NaN mixing which is better than but inconsistent with SSE NaN mixing. Software remainder() would probably have been inconsistent with software remainderl() for the same reason if the latter existed.
Signaling NaNs cause further inconsistencies on at least ia64 and i386.
Use __FBSDID().

Fix formatting, this is hard to explain, so I'll show one example.
- float ynf(int n, float x) /* wrapper ynf */ +float +ynf(int n, float x) /* wrapper ynf */
This is because the __STDC__ stuff was indented.

Assume __STDC__, remove non-__STDC__ code.

Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

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. -- End comments
