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.

* cygwin.din: Eliminate _strace_wm. * sigproc.cc (wait_sig): Temporarily add more debugging output. * include/cygwin/version.h: Bump minor api to reflect export change.
