[ocaml-platform] Passing flags to the OCaml configure script?

[Anil Madhavapeddy]

Are you on a 32-bit platform by any chance?  If you clone:
http://github.com/OCamlPro/opam-repository

and look in the compilers/ directory, you can copy one of those into a custom compiler.  Several of them define custom configure flags (look at the debug runtime one).

You can use the local cloned repository via

$ opam remote add dev <directory>

and the new compiler should appear.
