Yes, I know msdos/int21.c contains lots of broken code and
I'm pretty sure your patch did not add any new bugs. I just
would prefer that instead of moving broken code around,
broken code would be removed from msdos/int21.c and fixed
code would be added to winedos/int21.c or at least comments
would be added to broken code saying that code is broken
and it needs to be fixed. This is because Wine DOS emulation
was horrible mess before I started working on it and it is
still a big mess after all my work and I really don't want to
see patches that make the mess worser than it is.

Well, I have been planning to write a patch that migrates those
int21 subfunctions but unfortunately I have not had the time to do
it. And as DOS event handling is currently more or less broken,
I guess migrating int21 subfunctions has even lower priority than
it had before.

So, if you want to submit patches that migrate code to winedos,
I won't really mind, as long as you try to either fix or comment
obviously broken code (Ralf Browns Interrupt List is really helpful)
and you try to make as much use as possible of existing winedos code.
