Let's just say my time to work on DJGPP V2 over the last 2 years has been
about 1/4 what I had originally planned - so many things which should have
been completed never made it.  HW interrupts, signals, and FPU emulation
in the debuggers never made it off the design notepad due to lack of time.
Debugging them is a bitch, since it needs to be done on a ram disk just
in case you forget to save a register and trash DOS, and each messup is
a reboot.  I have a copy of ldbg ported to V2 which is in limbo due to
a legal naming mess, so I haven't done anything with it other than let
it sit.  I know it allows serial port debugging.  I don't remember where
I put it ...
