fseeko is in stdio.h but guarded:


#if _XOPEN_SOURCE>=500
#include <sys/types.h>
extern int    fseeko __((FILE *, off_t, int));
extern off_t    ftello __((FILE *));

I'm not sure if that has been fixed in gnulib yet or not, but you can
find out by testing the recent snapshot:

Already fixed in git.  I'd release 1.4.15 already, except that there is
a regression on AIX that I still haven't been able to figure out.
