kconfig: make kconfig MinGW friendly
Kconfig is powerfull tool. So powerfull that more and more software projects are using it for configuration. So instead of fixing some of them one by one, lets fix it in kernel and wait for sync. This work was originaly done for PTXdist - GPL licensed build system for userlands and cross-compilers, but it will not hurt kernel kconfig either. PTXdist menuconfig now works on Windows linked with PDCurses and compiled using MinGW - there is no termios and signals. * Do not include <sys/wait.h> and <signal.h> (comes from times when lxdialog was separate process) * Do not mess with termios directly and let curses tell screen size. Comment to commit c8dc68ad0fbd934e78e913b8a8d7b45945db4930 says check for screen size could be removed later, but because it didn't happen for more than year I left it here as well. * Save cursor position added by Sam Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Cc: Roman Zippel <zippel@linux-m68k.org>
