at runtime.
etc/make.conf:
Nuked HAVE_FPU option.
lib/msun/Makefile:
Always build the i387 objects. Copy the i387 source files at build
time so that the i387 objects have different names. This is simpler
than renaming the files in the cvs repository or repeating half of
bsd.lib.mk to add explicit rules.
lib/msun/src/*.c:
Renamed all functions that have an i387-specific version by adding
`__generic_' to their names.
lib/msun/src/get_hw_float.c:
New file for getting machdep.hw_float from the kernel.
sys/i386/include/asmacros.h:
Abuse the ENTRY() macro to generate jump vectors and associated code.
This works much like PIC PLT dynamic initialization. The PIC case is
messy. The old i387 entry points are renamed. Renaming is easier
here because the names are given by macro expansions.
eliminates the "X-authentication-warning" header line that
has been coming out since I made it so that sendmail is
run totally as the user whose calendar file is currently
being processed.
log10(x) = log10e * log(x). The formula would work if the RHS were
evaluated in extended precision with an extended precision log().
This actually happened with the i387 log() because it returns excess
precision.

Opps! Forgot to add Jordan K. Hubbard for his xspringies port.
history was lost with FreeBSD-1.x and they were blown away
by the gdb-4.16 merge. I needed this to debug e_exp.S ...
Restored even older code (from 386BSD-0.0) for converting the
FP registers to doubles. floatformat_to_double() and/or
valprint() still don't understand NaNs.
Removed unnecessary #include of obsolete <sys/dir.h> again.
"%%" in format strings and tends to dump core for "%%st". I needed
"%%st" to fix the new gdb ...
Don't use the private version of strerror() either.
Use INTERNALLIB and INTERNALSTATICLIB instead of a private install
rules NOPROFILE and NOPIC. This is only slightly cleaner.
INTERNALLIB was previously only used in compatibility libraries
(libgnumalloc etc.) and INTERNALSTATICLIB was previously unused.
INTERNAL*LIB probably should be replaced by something like NOSTATICO
together with NO{STATICO,PROFILE,PIC}INSTALL.
Now that this is becoming (dare I even say it?) more useful for
post-configuration, no longer leave sysinstall.debug files around
by default. Only do this if environment variable SYSINSTALL_DEBUG
is set.
This defeats the point of log1p(). ucbtest reports errors of +-5e+15
ULPs. A correct version would use the i387 fyl2xp1 instruction for
small x and maybe scale to small x. The C version does the scaling
reasonably efficiently, and fyl2px1 is slow (at least on P5s), so not
much is lost by always using the C version (only 25% for small x even
with the broken i387 version; 50% for large x).
