specpdl overflow here, to simplify callers; all callers changed.

Also, prefer report_file_errno to setting errno + report_file_error.

Minor EBADF fixes.

* process.c (create_process, wait_reading_process_output) [AIX]:
Remove obsolete SIGHUP-related  code, as Emacs no longer disables
SIGHUP, so EBADF is no longer acceptable here (it wouldn't work in
a multithreaded environment anyway).
* sysdep.c (emacs_close): It's not dangerous to invoke emacs_close (-1).

lisp/desktop.el: Minor fixes.

New macro and function, which emulates the POSIX_CLOSE_RESTART macro

(emacs_close): Use it.  This should fix the races on GNU/Linux and
on AIX and on future platforms that support POSIX_CLOSE_RESTART,
and it should avoid closing random victim file descriptors on
other platforms.

lisp/emacs-lisp/cl-macs.el: Fix typos in docstrings.

All uses changed.  Now a function, not a macro; use this fact
to simplify the code.

compiler bugs; no longer relevant.
* syntax.h: Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
(SYNTAX_INLINE): New macro.

for the new functions.  Use bool for boolean member.

case of error.  Improve messages.

condition-case.  Call `tramp-error-with-buffer' with vector and buffer.

(tramp-maybe-open-connection): The car of
`tramp-current-connection' are the first 3 slots of the vector.

* src/systime.h (make_emacs_time, invalid_emacs_time):
