Yeah, I thought so at first, but looking closer I think it's not too
relevant to the problem.  This is for testing whether a couple of *other*
macros need to be defined, it's not about _LARGEFILE_SOURCE.

Well, I think 2.61's treatment of fseeko is simply broken.  I'm tempted
to propose fixing this by defining PGAC_FUNC_SEEKO the same way 2.59
defined AC_FUNC_SEEKO, and then we wouldn't need the changes you've been
making.

But someone ought to kick this upstream and ask what they were thinking.
