appropriate.
(LIBCOS): Find additional stub library stuff in their own subdirectory.
* dcrt0.cc: Convert user_data pointer to static __cygwin_user_data area.
(do_global_ctors): Check magic_bisquit for initialization.
(dll_crt0_1): First group of premain functions prior to fd initialization.  Run
second group before calling main.
(dll_crt0 ()): New function, called from new initialization code.
(dll_crt0 (per_process *uptr)): Call new dll_crt0 () function on
initialization.
