Following reports that -fwrapv has known issues in GCC prior to version 4.2,
use '-O' (and warn) for GCC [3.0, 4.2);
use '-O2 -fwrapv -fno-strict-aliasing' for GCC 4.2 and up.

Auxiliary changes:
- Put GCC in gnu99 mode (= C99 + GNU extensions).
- Check C99 conformance, warn if not.
- Reject if gcc is too old ( < 3.0 )
- Stop C compilation on warnings if this is a development version of OCaml.
(I'm tired of C warnings being ignored.)

configure: deselect ocamlopt, which is not supported
signals_machdep.h: use i386 instruction sequence, not amd64.

- Removed MacOS X support, long dead.
- Added support for PowerPC 64 bits, big-endian, ELF v1 ABI
(tested, mostly works, some issues remain with marshaling of code pointers)
- Added support for PowerPC 64 bits, little-endian, ELF v2 ABI
(completely untested)

NB: after applying this change you need to run ./configure again.

- configure: no change necessary
- byterun/config.h: make sure ARCH_INT64_TYPE and related macros
are always defined, for Coq and others to use.

and maybe others rely on it
byterun/config.h: select "long long" in preference to "long" for "int64",
just because this is how it was done in earlier versions.
(Minimizing suprises.)

An ISO C99-compliant C compiler and standard library is now assumed.
(Plus special exceptions for MSVC.) In particular, emulation code for
64-bit integer arithmetic was removed, the C compiler must support a
64-bit integer type.

-C doesn't work on at least openbsd's make so don't use it.

This script was built from ocamlcomp.sh.in through sed and is called
instead of "ocamlc" (for instance).
It makes it possible to switch from "ocamlc" to "ocamlc.opt" without
changing anything in the Makefiles, only calling sed.
I couldn't cleanly make it handle both a compiler for the target and for
the build. Instead I'm replacing it and doing as much as possible
directly in the Makefiles.
I hoped it would reduce the number of shell invocations, which would
speed things up quite a lot on Windows but I still had to have at least
one since it's not possible to update a make variable from inside a make
rule: i.e. it's not possible to do X=a, build a.opt and update X to be
a.opt.

This doesn't touch the build system in build/ since it's obsolete and
unmaintained as far as I know (I'll try to remove it in a further
commit).

This makes the variable names more coherent and is in preparation for
another patch that will allow disabling ocamldoc and ocamlbuild.
This changes the interface of the configuration somewhat but I don't
think anything outside of the ocaml tree reads the Makefile.config file
that gets installed in order to see whether the debugger and camlp4 have
been built. It also changes a .mli which might be problematic but I also
believe it is safe and we have time to see if there's a bad impact.
It also adds a configure switch to skip building ocamldebug.
While at it, it fixes a PR number in the Changes file.
