Indeed. However, some people might want to recompile them (e.g. to keep
debug symbols, or to use a specific version of their C compiler).

As far as I can tell, the install target does not copy these files.

No.

You're right about the circular dependency, but the answer is much
simpler than for the chicken-and-egg question: OCaml came first.
I don't see a compelling reason to include a binary version of flexdll
in the OCaml distribution. Just consider flexdll as an external
dependency that comes in binary form (like the MS C compiler). It just
happens to be produced by the OCaml compiler.

Note that flexlink.exe can be compiler with an old OCaml compiler. Also,
if you insist to bootstrap everything, it shouldn't be too difficult to
get a minimal (=no dynamic linking of external C code) ocamlrun.exe for
3.11 that does not require flexlink.
