them all compiling.
Tweaks include updating
ocaml-batteries 2.3.1 -> 2.5.0
ocaml-lwt 2.4.8 -> 2.5.2
ocaml-ppx-tools 0.99.2 -> 4.03.0
ocaml-camlp4 4.02+6 -> 4.03+1
utop 1.15 -> 1.19.2
and fixes to coccinelle and wyrd to let them build on bytecode archs.
Other necessary tweaks from the various homes of the projects.
Everything still builds on amd64 (native and bytecode) and sparc64 (bytecode).
ok anil@ sthen@ so final 4.3.0 tweaks can be done in-tree.
add / change BUILD_DEPENDS for all ports using camlp4.
Findlib is changed because it won't use camlp4 and doesn't install
the Bytes module anymore, which is now included in OCaml 4.02.
ok avsm@
This will work with OCaml 4.02. Always use -enable-pcre,
because Netstring_str will now use the builtin Str module,
while Netstring_pcre will use ocaml-pcre.
ok avsm@
