(usage): Mention -m option as ignored.
(main): Drop support for -m option. Mark ignored options as deprecated.
* utils.sgml (mkpasswd): Remove description of -m option.
directly. Drop support for older Cygwin DLLs. Just use progname_long
as is since it's already a POSIX path now. Rename "tty" to "pty" as in
the Cygwin DLL. Call setlocale to make sure wcstombs does the right
thing according to the current locale.
* Makefile.in (ps.exe): Link against psapi.dll.

* sigproc.cc (signal_exit): Move here. Declare stackdump extern. Set
my_sendsig to indicate that signals are no longer available.

errno setting, just setting errno generally, even for "its_me" case.

lock_process.

required for it.
* include/sys/strace.h (strace::hello): Delete.
(strace::write_childpid): Delete first argument.
* dcrt0.cc (get_cygwin_startup_info): Signal readiness when stracing since
strace::write_child relies on it. Use strace.activate to notify strace
process, passing in arg indicating whether we're forked.
* sigproc.cc (wait_sig): Accommodate new strace::activate argument.
* spawn.cc (child_info_spawn::worker): Oops. Previous suspended test was
actually correct. Revert and document.

an attempt to activate a forked process.

rather than as C statements and make sure that flags is set to zero initially.

get a more appropriate message based pipe.

by calling NtQueryAttributesFile. Make STATUS_DIRECTORY_NOT_EMPTY
return value dependent on its status code. Add long comment to explain.

Set status to STATUS_SUCCESS instead of 0. Add a retry loop to setting
the delete disposition and trying to move a directory to bin to
workaround rare cases of lingering, already deleted subdirectory
entries. Add long comment to explain.
(rename): Set status to STATUS_SUCCESS instead of 0.
succeeds. Return true for success.
* sigproc.cc (child_info_spawn::reattach_children): Try harder to clean up on
error by detecting reattach failures too.
