The "autoconf-2.53-target_prefix" patch is not going to be accepted for
autoconf as it contradicts the new principle of choosing cross-compilation
configurations introduced with autoconf 2.50. It's needed for the ability
to set target_alias without triggering a cross-compilation setup.
However, this is not the right solution -- I took part in a discussion at
the binutils list a while ago where the right way to solve this was
proposed and accepted by an autoconf maintainer. I had no time to
implement it so far and I may still be unable to do that for quite some
time now. It's needed for the top level only anyway and I think the top
level has a workaround for this deficiency of autoconf. It can be safely
ignored for gdb/ and sim/.
The "autoconf-2.58-catfile" patch is indeed needed, but I am told this
problem has been resolved with autoconf -- I'll do a check with the patch
reverted.

I'll ask the autoconf maintainers if there is hope for the AC_REQUIRE bug
to be fixed soon -- the hack to work it around for sim is ugly enough I'd
prefer to avoid it in the mainline.
If you want to convert gdb/ and sim/ to 2.5x, then I have a set of three
patches that are necessary or useful. They are: "gdb-5.2-long-double",
"gdb-6.0-ah" and "gdb-6.0-sim-ac25". I'll send them shortly.
