Is there something special about bigarray in ocaml 3.10 (for example some special settings at the installation are needed in order for bigarray to work correctly).

I have sourcecode of a program using c_stubs and bigarray. With my
ancient Makefile (using OCaml 3.09) everything works fine, but using
ocamlbuild (OCaml 3.10) I get following array message in the only
C-function that uses a macro related to bigarray (namely
alloc_bigarray_dims):

undefined reference to `alloc_bigarray_dims'
collect2: ld returned 1 exit status
Error during linking
Command exited with code 2.
