* dcrt0.cc (dll_crt0_1): Don't close hexec_proc if it is NULL.

Browse Source 
* fork.cc (vfork): Add debugging statements.
* path.cc (get_device_number): Make static.  Rewrite to inspect both unix and
windows paths.
(get_raw_device_number): Just check for parts of raw device that we care about.
(get_devn): New function, pulled from get_device_number.
(win32_device_name): Accomodate arg changes to get_device_number.
(mount_info::get_device_number): Call get_device_number on translated Windows
path.
* spawn.cc (spawn_guts): Don't treat P_VFORK differently from P_NOWAIT.  Add
handle to child's shared region to child so that it will be preserved if the
parent goes away.
* fhandler.h: Throughout, simplify to one open method for all fhandler classes,
requiring a path_conv first element.
* fhandler.cc (fhandler_base::open): Remove obsolete method.  Generalize to
require path_conv * as first argument.
(fhandler_disk_file::open): Remove obsolete method.
(fhandler_disk_file::open): Use path_conv pointer rather than reference.
* fhandler_clipboard.cc (fhandler_dev_clipboard::dup): Use new open method.
(fhandler_dev_clipboard::open): Accomodate new argument for open methods.
* fhandler_console.cc (fhandler_console::open): Ditto.
(fhandler_console::dup): Use new open method.
(fhandler_console::fixup_after_fork): Ditto.
(fhandler_console::fixup_after_exec): Ditto.
* fhandler_dsp.cc (fhandler_dev_dsp::open): Accomodate new argument for open
methods.
* fhandler_floppy.cc (fhandler_dev_floppy::open): Ditto.
* fhandler_mem.cc (fhandler_dev_mem::open): Ditto.
* fhandler_random (fhandler_dev_random::open): Ditto.
* fhandler_raw.cc (fhandler_dev_raw::open): Ditto.
* fhandler_serial.cc (fhandler_serial::open): Ditto.
* fhandler_tape.cc (fhandler_dev_tape::open): Ditto.
* fhandler_tty.cc (fhandler_tty_slave::open): Ditto.
(fhandler_pty_master::open): Ditto.
* fhandler_windows.cc (fhandler_windows::open): Ditto.
* fhandler_zero.cc (fhandler_dev_zero::open): Ditto.
* fhandler_socket.cc (fhandler_socket::set_connect_secret): Accomodate new
argument for open methods.
* syscalls.cc (_open): Ditto.
(stat_worker): Ditto.
