From 768761820e8d7481c586c4e0ab4ac7cb36d18c4b Mon Sep 17 00:00:00 2001

Subject: Added the same open()/fopen()/creat()/mmap() -> sys_XXX calls.

Tidied up some of the mess (no other word for it). Still doesn't
compile cleanly. There are calls with incorrect parameters that
don't seem to be doing the right thing.

This code still needs surgery :-(.

Jeremy.
