* cygerrno.h: New file. Use this throughout whenever errno manipulation is 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 /.

/* cygerrno.h: main Cygwin header file.
* cygerrno.h (set_errno): Set global errno whenever setting thread specific version. * debug.cc (__set_errno): Ditto. * exceptions.cc (handle_sigsuspend): Remove spurious sig_dispatch_pending call. (set_signal_mask): When there seem to be pending signals to dispatch, tell signal_dispatch_pending/sig_send not to specifically call any handlers. * sigproc.h (sig_dispatch_pending): Change declaration to void. * sigproc.cc (sig_dispatch_pending): Change definition to void. Take an argument to determine whether to tell sig_send to wait for handler to be called. * sigproc.cc (sig_send): Don't call signal handler when sig == __SIGFLUSHFAST. (wait_sig): Honor __SIGFLUSHFAST. Guard against sigpacket::process nuking si_signo. * sigproc.h (__SIGFLUSHFAST): Define new special signal. (sig_dispatch_pending): Change declaration to void. Take optional boolean argument. * fork.cc (vfork): Add debugging output.
