	I've been working on the v9alt build for the last while, so take this
with a grain of salt, but my understanding was that the v9 build for Osi
0.104 is entirely broken due to rearrangement of the Osi code tree
between 0.103 and 0.104. We're working on it; if you're interested in
helping, send me an email off-list and I'll add you into that email
conversation. If you're trying to mix and match over the past couple of
stable versions, you're definitely headed for trouble.

	The v9alt build is a completely different philosophy. I need to hunt
around to see where I put the instructions for using it. Again, if
you're interested, send me an email.

  The above says that OsiAuxInfo.obj is not being linked into the build,
which implies that it's not being linked into libOsi, which is a bit
baffling because it's in the libOsi.vcproj file for 0.103. No good
explanation off the top of my head.

	Again, no good explanation, and it's been even longer since I tried a
Cygwin build. I'm going to hope that someone else will field this one.
