I think you're looking for the opposite question. MPI_AINT_CAST_TO_VOID_PTR is used throughout the MPICH code base. ROMIO should use MPI_AINT_CAST_TO_VOID_PTR, providing it's own (stubed out?) version if that macro is not available.

You're calling MPI_AINT_CAST_TO_VOID_PTR from glue_romio.h. I don't know which way all your dependencies run, but why not have all the ROMIO code use a ROMIO version of the macro (something that is always available)?
