Hi Miller, On my windows machines (XP and 8.1), if I tried to open with mode 'r', the later call to ov_open would fail. If I change the mode to 'rb', the later call to ov_open works fine. I also read somewhere that the 'b' mode does nothing on Unix (I still have to test that when I'm back to my Linux and Mac machines).
As for the comparison against NULL, the original code was comparing if((x->x_file = sys_fopen(filename->s_name, "r")) < 0) And I changed it to <= instead. You are right in that it makes no sense to compare the sign of a pointer so == it is :) R.
