I dont; recall seeing such a usage but thinking about it a bit more
deeply, and possibly echoing another poster, "--enable-something" is
normally used for something optional as in the fuller form



whereas options that configure the "something" are often the "--with"

For example, from OpenMPI,

--enable-mpi-f90     enable f90 MPI bindings (default: enabled)

and then,

                     specify the types of functions in the Fortran 90 MPI
                     module, where SIZE is one of: trivial (MPI-2 ...

                     The maximum array dimension supported in the F90 MPI
                     bindings (default: $OMPI_FORTRAN_MAX_ARRAY_RANK).

Apologies for the noise,
