AC_FUNC_FSEEKO was rewritten for 2.61, but a typo rendered it broken in

This is exactly why I hate relying on cache variables.  :)

Relying on documented cache variables is fine.  But you are correct that
relying on undocumented cache variables tends to be problematic.

It appears that most of the cache variables set by autoconf are undocumented (and that of those which are, several such as the ones related to compiler checks have changed over the years).

Perhaps the autoconf documentation should be improved, to note this problem.
