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 /.
* *.cc: put winsup.h before other headers (for __INSIDE_CYGWIN__);
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.
* debug.cc (threadname_init): Pass name of lock as arg 2 of new_muto.
* malloc.cc (malloc_init): Ditto.
* sigproc.cc (sigproc_init): Ditto.
* exceptions.cc (events_init): Ditto.
(call_handler): Eliminate special case for hExeced. Report locked thread in
debugging output.
* fhandler.cc (fhandker_pipe::fhandler_pipe): Propagate device type to base
class.
* fhandler.h (fhandler_pipe): Ditto.
* hinfo.cc (hinfo::build_fhandler): Pass specific type of pipe to constructor.
* spawn.cc (spawn_guts): Eliminate dependency on signal when waiting for
subprocess.
* strace.cc: Remove obsolete #ifdef.
* sync.cc (muto::muto): Save the name of the muto.
(muto:~muto): Also release the muto.
* sync.h: Add a muto name field.
* select.cc (peek_pipe): Avoid doing a PeekNamedPipe on the write end of a
pipe.
* fhandler.h: Declare new function. Add extra argument to
process_slave_output.
* fhandler_console.cc (fhandler_console::read): Move read ahead code to new
function.
* fhandler_tty.cc (fhandler_pty_master::process_slave_output): Move common code
here.
(fhandler_tty_slave::read): Understand readahead.
(fhandler_pty_master::read): Move code to process_slave_output.
* select.cc (peek_pipe): Avoid performing certain checks when non-read and on
inappropriate fh types.
on interrupt if executing in a "cygwin" thread.
* fhandler_tty.cc (fhandler_pty_master::process_slave_output): Streamline,
simplify code.
* sigproc.cc (sig_send): Remove debugging statement.
* exceptions.cc (sfta): Eliminate obsolete function.
(sgmb): Eliminate obsolete function.
(class stack_info): Remove MS method for walking the stack.
(stack_info::init): Just initialize required fields.
(stack_info::brute_force): Rename to stack_info::walk.
(handle_exceptions): Pass derived frame pointer to sig_send.
(interrupt_setup): Clear saved frame pointer here.
(interrupt_on_return): thestack is no longer a pointer.
(call_handler): Accept a flag to indicate when a signal was sent from other
than the main thread. Use saved frame pointer for determining where to place
signal handler call.
(sig_handle): Accept "nonmain" argument. Pass it to call_handler.
* fhandler_tty.cc (fhandler_tty_common::__acquire_output_mutex): Change
debugging output slightly.
* (fhandler_tty_common::__release_output_mutex): Ditto.
(fhandler_tty_slave::read): Fix a comment, remove a goto.
* sigproc.cc (sig_send): Accept an optional frame pointer argument for use when
suspending the main process. sigcomplete_main is an autoreset event now. Save
frame pointer for non-main operation.
(wait_sig): Make sigcomplete_main an autoreset event. Eliminate NOSIGQUEUE.
Pass rc to sig_handle to signify if this was a nonmain process.
* sigproc.h: Reflect change to sig_send argument.
* syscalls.cc (swab): Eliminate swab function since it is now available in
newlib.
* winsup.h (signal_dispatch): Change CONTEXT cx to DWORD ebp.
