2011-12-08  Christopher Faylor  <me.cygwin2011@cgf.cx>

        * dll_init.cc (dll_dllcrt0): Don't try to initialize dll data if we're
        dynamically loaded since fork() doesn't work in that scenario anyway.
        (dll_dllcrt0_1): Don't accommodate dynamically loaded dlls.
        * exceptions.cc (ctrl_c_handler): Don't lock the process; there's too
        much risk of deadlock.

        the waitq if there is obviously nothing there.
        * strace.cc (strace::activate): Allow stracing dynamically loaded
        cygwin1.dll.

2011-12-07  Christopher Faylor  <me.cygwin2011@cgf.cx>

        to zero initially.

2011-11-21  Christopher Faylor  <me.cygwin2011@cgf.cx>

        rd_proc_pipe here.  Close it when we actually are finished with the

        child_info_spawn::cleanup on function return.
        (spawnve): Reflect movement of spawn_guts functionality into
        child_info_spawn::worker.
        * syscalls.cc (popen): Ditto.

        (fhandler_pty_master::setup): Allocate tty here.  Rely on handles being
        returned from allocated test rather than opening them here.  Avoid
        setting _need_nl here since it is already zeroed in the constructor.

        access.
        (tty::not_allocated): Clarify comment.  Rename.  Return handles when an
        unused tty is found.  Simply test for existing tty.
        (tty::exists): Rewrite to use `not_allocated'.
