TARGET_SUBDIR cannot be . anymore.
* Makefile.in: Regenerate.
* cygthread.cc (cygthread::stub): Add better debug output.
(cygthread::cygthread): Ditto.

longer required.

SIGTERM.
(proc_waiter): Detect if exit code is unset and use status from
GetExitCodeProcess.

proc_waiter now (again) detects it.

(_pinfo::exit): Reflect move of alert_parent. Set procinfo to NULL to flag
that we are exiting normally. Always use exitcode when exiting
(although this could be a little racy).
(pinfo::init): Set default exit to SIGTERM. This will be the exit code
reported if process is terminated.

(pinfo::wait): Duplicate wr_proc_pipe to the right place. Use dup_proc_pipe to
move the pipe to the child.

before using it.

error.

set inuse or suffer potential races.

(path_conv::set_normalized_path): Strip trailing dots, similarly to what had
previously been done for the win32 path.

slightly to eliminate extra variables.

* child_info.h (CURR_CHILD_INFO_MAGIC): Use updated value.
* path.cc (path_conv::check): Check the output Win32 path for trailing spaces
and dots, not the input path. Disallow all use of foo./bar since consistently
getting this right is time consuming. Remove strange test for "unc\" since no
one seems to know what it's for.
* sigproc.cc (proc_subproc): Fix long-standing problem. Only wait for "all
processes" if pid == -1 -- not just if pid is negative.
(proc_can_be_signalled): Fix another long-standing problem. Set correct errno
