You do not need to test whether they exist: try to move them and ignore
the error if there is any. Now, if you really want to test the existence
of some executable files, "test -x" is not so difficult to use.

Difficult to agree on what The Right Thing is, but as for elegance, the
introduction of 0 in arithmetics solved many problems very elegantly;
mathematicians would not work without the emptyset, and shell
programmers find /bin/true and /bin/false very convenient; I would not
program in OCaml without the empty list. All these are very elegant
concepts. I do not understand why an empty package would not be elegant?

Yes, but I guess the buildd will check that there is a Build-depends and
rebuilt automatically?

I think you missed the point: there is no single "current version of
ocaml". There is the version of unstable, the one of testing, and the
one of stable. I want my package to compile on as much as versions as
possible (as for the current version of Coq, it cannot compile on stable
but it can compile on testing; in fact, I did not even needed to check
my package compiled on unstable: I know it will compile as it is ok on
testing and the upstream Coq has been ported to ocaml-3.04).

This might indeed be a good idea (it requires no more nor less work than
providing an empty package). Or even better: provide an ocaml-best
package in ocaml-native-compilers and provide this package when there is
no optimized compiler.
