* fhandler.cc (fcntl): Print flags in hex.

* dcrt0.cc (dll_crt0_0): Semi-revert 2006-03-14 change which moved pinfo_init
and uinfo_init here.
(dll_crt0_1): Ditto.
(__dll_crt0): Ditto.  Don't call update_envptrs here.
(dll_crt0_1): Ditto.  Move wait_for_sigthread call here from dll_crt0_0.
* environ.cc (environ_init): Call it here instead.
* sigproc.cc (my_readsig): New static variable.
(wait_for_sigthread): Set up read pipe here since we are assured that we have
the proper privileges when this is called.
(talktome): Eliminate second argument since it is available as a global now.
(wait_sig): Reflect use of my_readsig.
