Windows CE port fixes/enhancements (from <Someone>)

A few other fixes:
- bug: text window does not scroll left on left arrow
- pcmain.c: fix warning: _fileno() returns void* in Windows CE SDK

3.5.0 only:
- files.c: compile error: don't include <signal.h> if NO_SIGNAL is defined. WinMo does not support POSIX signals
- version.c: compile error: append_port_id() is undeclared
- link error: mktime() is unsupported -> define it in celib.c
