Darn. Pushed the obvious fix of adding a direct fmgr.h include, rather
than the preivous indirect include.

Hm. I don't understand why it's not complaining. Wonder if it's a
question of the flags or such.

I noticed that "manually" earlier, when looking at the openbsd issue.

I wonder if we should just add a #ifndef HEADERCHECK or such to the
headers that we don't want to process as standalone headers (or #ifndef
NOT_STANDALONE or whatever). That way multiple tools can rely on these markers,
rather than copying knowledge about that kind of information into
multiple places.
I wish we could move the whole logic of those scripts into makefiles, so
we could employ parallelism.
