May well be fixed by an update to SWIG. This is a problem with all the
areas we're using SWIG and defining types. Swig doesn't understand (or
keep track of) when we're defining typedefs, so its getting conflicts
in various places for various reasons. It was a huge pain to diagnose
and figure out because a fix on 32-bit machines broke the 64-bit, and
vice versa. Frankly, I was just hoping that by keeping silent and
ignoring it, the problem would go away....

The solution is in commit 8088f125a9a (on Mar. 29). I'm not sure why
it really started, honestly, but it seems related to the removal of
gruel and some delicate balance we had working beforehand. Why it's
happening again, I'm not sure. With luck, though, upgrading SWIG to >
2.0 wll fix it.
