Using OSLib in relocatable modules

[Simon Callan]

I'm currently playing around with the RISC OS port of Python, trying
to put it into a relocatable module. It does not look to difficult,
except for one problem.

The current port uses the following functions.

  xdrawfile_render
  xdraw_process_path
  xosfile_create_dir
  xosfile_load_stamped_no_path
  xosfile_read_no_path
  xosfile_read_stamped_no_path,
  xosfile_save_stamped
  xosfile_set_type
  xosfile_stamp
  xosfile_write_attr
  xosfscontrol_canonicalise_path
  xosfscontrol_dir
  xosfscontrol_file_type_from_string
  xosgbpb_dir_entries
  xos_read_var_val
  xos_set_var_val
  xos_swi_number_from_string

As far as I am aware, there is no RM version of OSLib, and I was
wondering what is likely to be the best solution to this. As I see it,
there are 3 options
1) Rebuild OSLib for relocatable modules.
2) Copy the appropriate sources into the Python build structure, and
build them in RM mode.
3) Throw out all the OSLib functions, and recide using the raw SWIs.

I think 2 is likely to be the best, but what is recommended?
