Why not?
In any case, attached is the code I've currently got. Comments/criticisms
most welcome.
FWIW, replacing the call to open() (strictly, _open() under win32) in
BasicOpenFile (fd.c) with this win32_open() allows the regression tests to
pass through the transactions, foreign_key, and alter_table tests without
locking up (which is what they currently do). All in all, the change looks
sound, however I make no guarantee that a corner case has not been missed.
[One thing I have noticed is that database directories don't get removed
when dropping the db, leaving a whole stack of empty directories when
running the regression tests in a loop. However, this could very well be
pre-existing.]
Cheers,
Claudio
