* dcrt0.cc (dll_crt0_1): Initialize mainthread stuff here before anything needs

it.
* sigproc.cc (sigproc_init): Move mainthread initialization out of here.
* sigproc.h (sigthread): Add init() method.
(sigframe): Don't try to initialize muto.
* sync.cc: Undef WaitForSingleObject to avoid recursion.
