Function 7303 is NOT supported on Win XP.

RB Intterupt list doc:
Notes:  on DOS versions which do not support the FAT32 calls, this function
          returns CF clear/AL=00h (which is the DOS v1+ method for reporting
          unimplemented functions)

Testing results:
    Carry regs.x.flags = 0x0002
    Error regs.x.ax = 0x7300

Any other suggestions?

This takes the count of issues specifically to do with DJGPP and Win 2K / XP
to two.  The other one is that GDB serial debugging doesn't work. I still
need to look at this once I get some free time (right!!!) . Other serial
comms program I have written  work okay.
