* cygtls.h (_threadinfo::call): Remove regparm declaration to work around compiler bug. * autoload.cc (TryEnterCriticalSection): Remove. * dcrt0.cc (dll_crt0_0): Delete inappropriate setting of _my_tls.stackptr to NULL since it has really bad consequences. Make 'si' an automatic variable. * cygtls.cc (_threadinfo::init_thread): Correct thinko which caused thread list to be allocated every time. * cygtls.h (CYGTLS_PADSIZE): Define as const int. * sync.h: Make multiple inclusion safe. (muto::next): Eliminate. (muto::exiting_thread): New variable. (muto::set_exiting_thread): New function.

(_threadinfo::find_tls): Ditto. * cygtls.h (_threadinfo::padding): Make zero length (for now?). * dcrt0.cc (dll_crt0_0): Move more initialization here from dll_crt0_1.
