Minimal portability fix for commit e1551f96e.

Older gcc versions are not happy with having multiple declarations
for the same typedef name (not struct name).  I'm a bit dubious
as to how well-thought-out that patch was at all, but for the moment
just fix it enough so I can get some work done today.
