readline: rltty.c: Declare ioctl() explicitly.
Commit Message
Under Darwin, ioctl() is declared in "sys/ioctl.h", but except for some
special control commands, we do not want to include "sys/ioctl.h". So
declare it explicitly, the related warning:
gcc -c -DHAVE_CONFIG_H -I. -I../../binutils-gdb/readline -DRL_LIBRARY_VERSION='"6.2"' -g -O2 ../../binutils-gdb/readline/rltty.c
../../binutils-gdb/readline/rltty.c: In function 'set_winsize':
../../binutils-gdb/readline/rltty.c:83:7: warning: implicit declaration of function 'ioctl' [-Wimplicit-function-declaration]
if (ioctl (tty, TIOCGWINSZ, &w) == 0)
