Thanks for the report.  However, this is lacking too many details for us
to know what to do about it.  What system is this on?  Can you provide a
sample configure.ac that demonstrates that the problem is in autoconf, as
opposed to a particular package's improper use of the AC_FUNC_FSEEKO
macro?  After all, AC_FUNC_FSEEKO (which is documented as detecting
ftello) sets _LARGEFILE_SOURCE on platforms where it is needed.
