* configure.in: Check for fseeko, ftello.
* configure: Rebuilt.
* config.h.in: Rebuilt.
* fio.h: Define FSEEK to be fseek or fseeko, depending
on configure's findings. Ditto for FTELL and ftell / ftello.
* backspace.c (f_back): Use FSEEK for fseek, FTELL for ftell.
* dfe.c (c_dfe): Ditto.
* due.c (c_due, e_rdue): Ditto.
* endfile.c (t_runc): Ditto.
* err.c (f__nowreading, f__nowwriting): Ditto.
* ftell_.c (G77_ftell_0, G77_fseek_0): Ditto.
* inquire.c (f_inqu): Ditto.
* open.c (f_open): Ditto.
* rdfmt.c (rd_ed): Ditto.
