2571c7f720 POSIX says that 0[xX] prefix is _optional_ even in base 16 case, make it 
really so.

"If the value of base is 16, the characters 0x or 0X may optionally
precede the sequence of letters and digits, following the sign if
present."

9fd7a48db0 Cut out the gordian handling of subnormals by bit fiddling, and 
instead use the FPU to convert subnormals to normals.  (NB: Further
simplification is possible, such as using the FPU for the rounding
step.)

This fixes a bug reported by stefanf where long double subnormals in
the Intel 80-bit format would be output with one fewer digit than
necessary when the default precision was used.

c47a0d494c Implement a custom print formatter (archive_string_vsprintf) 
for libarchive error messages.  Mostly, this
avoids a portability headache related to
copying va_list arguments (some FreeBSD 5
platforms require va_copy; FreeBSD 4 doesn't
support va_copy at all).  It also dramatically reduces the
size of libarchive for embedded applications:
a minimal "untar" program using libarchive can now be
under 64k statically linked (as opposed to ~100k
using library *printf() functions).

851e420fba Add a file missed in the previous commit: 
Eliminate gdtoa.mk and move its contents to ${MACHINE_ARCH}/Makefile.inc.
  The purpose of having a separate file involved an abandoned scheme that
  would have kept contrib/gdtoa out of the include path for the rest of libc.

b6e65225a6 Most libm routines depend on the rounding mode and/or set exception 
flags, so they are not pure.  Remove the __pure2 annotation from them.
I believe that the following routines and their float and long double
counterparts are the only ones here that can be __pure2:

	copysign is* fabs finite fmax fmin fpclassify ilogb nan signbit

When gcc supports FENV_ACCESS, perhaps there will be a new annotation
that allows the other functions to be considered pure when FENV_ACCESS
is off.

ce4e53c460 Set math_errhandling to MATH_ERREXCEPT. Now that we have fenv.h, we 
basically support this, subject to gcc's lack of FENV_ACCESS support.
In any case, the previous setting of math_errhandling to 0 is not
allowed by POSIX.

f365db00e5 Mark all inline asms that read the floating-point control or status 
registers as volatile.  Instructions that *wrote* to FP state were
already marked volatile, but apparently gcc has license to move
non-volatile asms past volatile asms.  This broke amd64's feupdateenv
at -O2 due to a WAR conflict between fnstsw and fldenv there.
