9d683ffd4b o Move the contents of <machine/floatingpoint.h> over to
<machine/ieeefp.h> where it belongs.
o  Remove the i386 specific inclusion of <machine/floatingpoint.h>
   from <ieeefp.h>, now that including <machine/ieeefp.h> is enough
   for all architectures.
o  Allow <machine/ieeefp.h> to inline the functions exposed by the
   headers by checking for _IEEEFP_INLINED_ in the MI header. When
   defined, prototypes are not given and it is assumed that the MD
   headers, when inlining only a subset of the functions provide
   prototypes for the functions not being inlined.

Based on patch from: Terry Lambert <tlambert2@mindspring.com>
Tested with: make release.

a7674320e9 On FPU exceptions, pass a useful error code (one of the FPE_...
macros) to the signal handler, for old-style BSD signal handlers as
the second (int) argument, for SA_SIGINFO signal handlers as
siginfo_t->si_code. This is source-compatible with Solaris, except
that we have no <siginfo.h> (which isn't even mentioned in POSIX
1003.1b).

An rather complete example program is at
  http://www3.cons.org/cracauer/freebsd-signal.c
This will be added to the regression tests in src/.

This commit also adds code to disable the (hardware) FPU from
userconfig, so that you can use a software FP emulator on a machine
that has hardware floating point. See LINT.

6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

1130b656e5 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.
