Hmm. So the "checking for fseeko" (from fseeko.m4 or fflush.m4) says that
fseeko is absent, but AC_FUNC_FSEEKO says that fseeko exists?! Can you show
more details from config.log,
  - from the "checking for fseeko" check,
  - from the "checking for _LARGEFILE_SOURCE value needed for large files" 
check?

And does your system have fseeko? (What do the includes files say? And the
manual pages?)

rpl_fseeko is a wrapper around fseeko. On systems which don't have fseeko,
these lines in lib/fseeko.c take effect:

#if !HAVE_FSEEKO
# undef fseek
# define fseeko fseek
#endif

i.e. rpl_fseeko becomes a wrapper around fseek.

Systems which don't have fseeko are OSF/1 4.0, Solaris 2.5.1, mingw. On at
least two of these, the gnulib fseeko module is known to work.
