* configure.ac (gl_INIT): Add gnulib stuff.
(fseeko, ftello, ttyname, isascii): Replaced the AC_REPLACE_FUNCS
by a simple check.
(putc_unlocked): Removed check. Not used.
(strsep, mkdtemp, asprintf): Replaced checks by gnulib checks.
(xsize): Added will probably come handy soon.
(CFLAGS): Use -Wformat-security instead of
-Wformat-nonliteral. Add --Wno-format-y2k.
* gl/, gl/m4/: New.
* gpg-agent.c: Include setenv.h.
* Makefile.am (AM_CPPFLAGS): Added.

function. Copied from ../common/ftello.c.
