======

GCC 4.3.0 release has been tagged in SVN, tarballs uploaded
to gcc.gnu.org (though not to ftp.gnu.org yet).
The branch is still frozen though, until we agree on what if
anything to do about the implied cld instructions on i?86/x86_64.
Hopefully this will not take long.

The options are do nothing (it is a kernel bug and it is easiest to fix
it there), or provide a workaround (don't need to step back to the old
way, where we inserted cld before string insns even when some function
was called since last time cld was emitted in the current function,
only one cld between prologue and any string insn in the function is
enough), where the workaround can be either optional (e.g. with default
determined at configure time), or unconditional, and can be used for
both -m32 and -m64 code, or just -m32 code (as in 64-bit code std is
extremely rare).
