GCC does not appear to have a -march= string for Westmere, which is a
bit surprising as it has a few more instructions than a Nehalem, but
a few less than a Sandy Bridge.

This is (erroneously) required to enable various things in the
newlib headers.  As cygwin uses newlib, it is covered by this.

A bug in tail call optimisation in gcc 4.3 and later on parisc causes
numerous tests to fail.  Disabling this optimisation gives a working
build.  See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55023

The -mpowerpc64 and -mpowerpc-gfxopt flags are implicitly set by
-mcpu as needed.  Passing them explicitly is redundant and can
conflict with user-supplied flags.

All modern assemblers have this capability.  Older NASM versions
that lack the capability produce code that crashes at runtime,
so it's better to error out during the build process instead.

Do not quote second argument to filter{,_out} in check_ld. We want to keep/remove all the space-separated words matching the -l* pattern, not keep everything if the whole argument begins with -l and remove it otherwise.

This also fixes errors like:
./configure: eval: line 418: syntax error near unexpected token `-l*'
./configure: eval: line 418: `case  in -l*) ;; *) echo  ;; esac'
when run with ./configure --enable-openal

Some awk versions do not treat the result of unary + on a (numeric)
string as numeric, giving wrong results when used in a boolean context
Using unary - instead is logically equivalent works as expected.

This is much faster with slow shells and noticeably faster even
with bash on a fast Linux system.

This isn't too useful as a normal codec, but can be used in
voip style applications. The decoder updates the noise
generator parameters when a packet is given to it for decoding,
but if called with an empty packet, it generates more noise
according to the last parameters.

This adds support for building on Plan 9 x86-32.  The compat/plan9
directory contains these items:

- replacements for the 'head' and 'printf' shell commands
- wrapper for main() to disable FPU exceptions

Larger required changes to the system are described in the
documentation.
