No difference. -dtype was superseded by -annot while ago. OCamlSpotter
extends these options to produce extra files for code browsing.

The patch does not touch any part of compilation, or at least I was
careful to keep the compilation part untouched. This means patched
compiler and the orignal should produce the same object codes. It
should be safe linking of objects from the original and the patched
together, as far as you use the same compiler versions. Of course,
there are no spot/spit files for library modules compiled by the
original compiler and you cannot browse them.

If you want to be very careful, use the patched compiler just for
spot/spit file creation and use the object files from the original
compiler. In this case you need to tweak your build scripts (Makefile,
OMakefile, ocamlbuild or whatever) somehow. Probably I can add
-annotonly option for the next version of OCamlSpotter to make it
easier.

I am not sure about the possibility of official integration of the
patch. Caml-dev team is generally conservative for a good reason: they
are responsible for keeping ocaml maintenable by themselves.
OCamlSpotter was made based on some non-trivial (probably wrong)
design choices. Maybe some people find OCamlWizard
(http://ocamlwizard.lri.fr/) is better. Or others like pretty heavy
weight solutions like Scion server for Haskell.
