* 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.

(new_muto1): Ditto. * dcrt0.cc (do_exit): Call muto::set_exiting_thread here. * sync.cc (muto_start): Eliminate. (muto::acquire): Always give exiting thread a lock. Never give thread a lock if exiting.

(lock): Accommodate switch to muto. (unlock): Ditto. * exceptions.cc (setup_handler): Don't worry about acquiring mutos since that hasn't mattered for a long time. (signal_exit): Ditto: muto stuff will be handled automatically on exit now. * Makefile.in (DLL_IMPORTS): Link advapi32 to ensure proper DLL initialization. * autoload.cc (RegCloseKey): Arbitrarily choose this function as a "seed" to pull the advapi32 link library in. So, comment out the autoloading. * cygtls.cc (_threadinfo::init_thread): Just clear CYGTLS_PADSIZE. (_threadinfo::remove): Add debugging. (_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.
