* 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.
