(wincapc::has_buggy_thread_startup): Ditto. * wincap.cc::wincap_*): Accommodate has_buggy_thread_startup. (wincapc::init): Explicitly turn off has_buggy_thread_startup if not WOW64. * cygthread.h (cygthread::thread_handle): Declare/define new method. * dcrt0.cc (_dll_crt0): Don't call __sinit here. (dll_crt0_0): Don't call sigproc_init during initialization if wincap.has_buggy_thread_startup(). (dll_crt0_1): Defer sigproc_init to here when wincap.has_buggy_thread_startup(). Call __sinit after we've determined that we're not forking. (__main): Rework comments. Add potential future reminder.
