including psapi.h.

is less than OPEN_MAX, the current dtable size otherwise.
* sysconf.cc (sysconf): Return getdtablesize () on _SC_OPEN_MAX.

about remote shares can take some time.

Patch by David Sainty <David.Sainty@optimation.co.nz>:
* resource.cc (setrlimit): Prevent failing with an error when the
operation would not have changed anything.
* exceptions.cc (stackdump): Avoid creating stackdump when
`rlim_core' is 0.
* resource.cc: New global variable `rlim_core'.
(getrlimit): New function.
(setrlimit): Ditto.
include/cygwin/version.h: Bump minor API version to 32 due to
adding `getrlimit' and `setrlimit'.
include/sys/resource.h: Add defines, types and prototypes for
`getrlimit' and `setrlimit'.
console_handler_thread_waiter. It is obsolete.
(ctrl_c_handler): Don't use console_handler_thread_waiter.

insensitive.

* pinfo.h (_pinfo): Avoid initializers for null case.
* resource.cc (fill_rusage): Zero rest of rusage structure.

(sigaction): Ditto.
* sigproc.cc (pchildren): Use default initializer.
(zombies): Ditto.
(sigproc_terminate): Avoid closing handles that will be closed on exit anyway.
(wait_sig): Send signal to "parent" on EXECing, not FORKing.
(wait_subproc): Send SIGCHLD here rather than in proc_wait to avoid potential
muto conflicts.
* sigproc.h (sigthread): Don't initialize to zero. It's the default.
* spawn.cc (spawn_guts): Fill in resources from exec parent prior to
termination.
* sync.h (muto): Don't initialize to zero.
* syscalls.cc (close_all_files): Use one lock around entire loop and call
fhandler close/release stuff directly.

* dcrt0.cc (dll_crt0_1): Fix display of "title".
(do_exit): Use pinfo exit method to exit.
(__api_fatal): Ditto.
* exceptions.cc (signal_exit): Ditto.

place of exec_fixup_after_fork.
* pinfo.cc (pinfo_fixup_after_fork): New method.
(pinfo_fixup_in_spawned_child): Ditto.
(_pinfo::exit): New method.
(_pinfo::init): Remove recursion. Detect pathological case where pinfo
structure already exists for new pid.
* pinfo.h (_pinfo): Reorganize slightly. Add new method and new function
declarations.
* sigproc.cc (proc_exists): Previous simplification was a little to simple.
Try harder to detect if a process exists.
(proc_terminate): Use PID_EXITED setting to determine if process is still
around.
(WFSO): Remove debugging statement.
(WFMO): Ditto.
* spawn.cc (exec_fixup_after_fork): Eliminate.
(spawn_guts): Always set old_title to NULL. Is it really needed? Move
hexec_proc to pinfo.cc. Call pinfo_fixup_in_spawned_child to eliminate handle
link after a spawn.
* include/sys/cygwin.h: Remove PID_NOT_IN_USE. Add PID_EXITED.
required.
* errno.cc: Use DWORD to hold Windows errors.
(geterrno_from_win_error): New function.
(seterrno_from_win_error): Use geterrno_from_win_error to convert supplied
windows error (suggested by Corinna Vinschen).
* path.cc (symlink_info): Add error element.
* path.cc (path_conv::check): Remove errno setting. Use new symlink_info errno
element to set path_conv error, where appropriate.
(symlink_info::check): Set error element rather than attempting to manipulate
errno. Add more checks for trailing / and /.. even though they are currently
useless. Avoid setting EINVAL.
* path.cc (normalize_posix_path): Correct check for trailing /.

use cur_environ() instead of just environ
* times.cc: remove import protections
* glob.c: add winsup.h
* localtime.c: ditto
* smallprint.c: ditto
* Makefile.in: don't __INSIDE_CYGWIN__ as it messes up profiling.
