* fhandler.h: Move fcntl.h include here. (fhandler_base::set_flags): Accept supplied_bin argument. Make non-inlined. * dtable.cc (dtable::init_std_file_from_handle): Just use binmode from pc. (reset_to_open_binmode): Use set_flags. * cygwin.din (open): Avoid newlib wrapper. (read): Ditto. (unlink): Ditto. (write): Ditto. * fhandler.cc (fhandler_base::set_flags): Accept supplied_bin argument. Make binmode decisions here. (fhandler_base::open): Avoid using pc if it is NULL. Eliminate binmode logic. Just call set_flags with binmode argument. (fhandler_base::init): Call set_flags with binmode argument. * fhandler_clipboard.cc (fhandler_dev_clipboard::open): Ditto. * fhandler_console.cc (fhandler_console::open): Ditto. (fhandler_console::init): Force binary on open. * fhandler_disk_file.cc (fhandler_disk_file::open): Don't set binmode here. Let it happen in base class. * fhandler_dsp.cc (fhandler_dev_dsp::open): Force binmode open. Set return value appropriately if unable to open. * fhandler_proc.cc (fhandler_proc::open): Make sure flags are set before open_status. * fhandler_process.cc (fhandler_process::open): Ditto. * fhandler_registry.cc (fhandler_registry::open): Ditto. * fhandler_random.cc (fhandler_dev_random::fhandler_dev_random): Ditto. * fhandler_raw.cc (fhandler_dev_raw::open): Force O_BINARY by default. * fhandler_serial.cc (fhandler_serial::init): Ditto. * fhandler_tty.cc (fhandler_tty_slave::open): Ditto.

(set_flags): Set PATH_TEXT explicitly, when appropriate. (mount_info::conv_to_win32_path): Use set_flags() to set path flags. * path.h (PATH_TEXT): New enum. (path_conv::binmode): Return appropriate constant based on binmode. * pipe.cc (make_pipe): Set binmode to O_TEXT xor O_BINARY. * syscalls.cc (setmode_helper): Make debugging message a little clearer.
