Well, that's what I have on my local system:
- Macro: AC_FUNC_FSEEKO
If the `fseeko' function is available, define `HAVE_FSEEKO'.
Define `_LARGEFILE_SOURCE' if necessary to make the prototype
visible on some systems (e.g. glibc 2.2). Otherwise linkage
problems may occur when compiling with `AC_SYS_LARGEFILE' on
largefile-sensitive systems where `off_t' does not default to a
64bit entity.
The "_LARGEFILE_SOURCE" bit is the important one -- I have a vague memory
of some program having a problem once in this area.

Well, I must have been blind. Or I'm simply too busy these days.
Anyway, sorry about the confusion and I'm glad you've got this right
despite the issues with LFS being too messy on many systems with no good
reason.
