This is probably ok to change.  I can only imagine that the original
author thought there might be cleanup needed at some later point.

cleanup usually does not warrant a new function.  This is exactly what
we use goto for.

This function is ugly, but not because it uses goto.  The function is
144 lines long, which is too long.  I'm not familiar with this code,
but I'm pretty sure some factorization is in order.  The level of
indentation could be reduced by breaking on failure instead of
proceeding on success.  Assuming this previous change is made, the use
of the goto would be that much more appealing.

Complete sentences go a long way towards effective communication :-)
The use of goto's cannot possibly be considered as a hack.  I also
don't see how you find goto's a problem when patching the code.

No, just send in a patch to wine-devel stating why you think the
change is correct.

P.S. Make sure you reply-all to cc wine-devel.  We're an open project
and we communicate openly so everyone can be a part of the discussion.
