(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. * util.h: Add some includes for gnulib. (ttyname, isascii): Define them inline. * fseeko.c, ftello.c: Removed. * strsep.c, mkdtemp.c: Removed. * ttyname.c, isascii.c: Removed. * mkdtemp.c: Removed. * exec.c: Include mkdtemp.h * keybox-file.c (ftello) [!HAVE_FSEEKO]: New replacement function. Copied from ../common/ftello.c. * keybox-update.c (fseeko) [!HAVE_FSEEKO]: New replacement function. Copied from ../common/iobuf.c. * scdaemon.c: Include mkdtemp.h. * misc.c: Include setenv.h. * symcryptrun.c: Include mkdtemp.h.
