d22ca8cdfb Make mantissa type configurable 
This allows the default mantissa to be integral, with powerpc
overriding it to take advantage of its FPUs.

e98cdb38ee Remove mention of i386-pc-linux-gnu. 
The GNU C Library does not support building for i386
therefore we remove mention of this configuration
from the INSTALL file.

4fdd5ec125 ia64: fix set-but-unused warnings with syscalls 
These macros often set up a variable that later macros sometimes do
not use.  Add unused attribute to avoid that.

Similarly, the ia64 code tends to check the err field rather than
the val (which is opposite of most arches) leading to the same
kind of warning.  Replace this with a dummy reference.

a186dc916c ia64: fix strict aliasing warnings with libm error 
The current code declares double constants by using a char buffer and
then casting the pointer to a different type.  This makes the aliasing
logic unhappy.  Change it to use a union instead to avoid that.

c5abd7ce01 ia64: fix strict aliasing warnings with func descriptors 
Function pointers on ia64 are like parisc -- they're plabels.  While
the parisc port enjoys a gcc builtin for extracting the address here,
ia64 has no such luck.

Casting & dereferencing in one go triggers a strict aliasing warning.
Use a union to fix that.

3c2ef5414f ia64: makecontext: fix signed warnings 
The ia64_rse_is_rnat_slot func expects an unsigned pointer, but we're
passing in a signed pointer.  The signness doesn't matter here, so
convert it to unsigned.

f5ad94e02a arm: Implement armv6 optimized string routines 
The strcpy and strchr (and related) functions are four times faster
than the byte-by-byte default versions.

The strlen function is twice as fast for long strings and 50% faster
for short strings over the armv4 version.

adbb8027be Remove PIPE_BUF Linux-specific code 
Fixes BZ #12723

The variable pipe buffer size does nothing to the value of PIPE_BUF,
since the number of bytes that are atomically written is still
PIPE_BUF on Linux.
