Well, in the abstract sense, this is the beauty of open source.  If the
pipe patches are causing problems then download the code, find the
patches that were added and reverse them and build your own DLL. 
There's a command-line option of 'patch' to apply a changeset in reverse
-- "-R" I think.

In the more realistic sense if there are things that are truly broken
about the DLL then they need to be addressed.  Nothing gets this done
faster than a simple test-case posted to the list that demonstrates the
issue.  But failing that it shouldn't be too hard to check out the
source from a certain date, or even check out the current source and
reverse a given patch-set.  There are instructions for building the DLL
on the website.
