VP sources aren't available (except for a small group of people who were
granted the right to work on fixes and updates in the past). Alan
officially rejected all requests to make VP sources publicly available
(only RTL sources were published) - most probably because his own rights
wouldn't allow that, or possibly because he might have been afraid of
possible troubles with Borland (pure speculation here). VP would be
certainly my preference (especially with regard to the compatibility level
with TP/BP and thus high reuseability potential for FPC).

BTW, I obviously forgot to mention OpenWatcom as another (OS/2) debugger
where the sources are available too.

I explicitely asked him via e-mail in the past whether he would be willing
to give us sources of the debugger part (immediately after he announced
official death of VP), but I didn't receive any response... :-(
