	winsup/cygwin  : ChangeLog dcrt0.cc exceptions.cc sigproc.cc 
	                 sigproc.h 

Log message:
	* dcrt0.cc (sigthread::init): Reinstitute sigthread lock as a critical section.
	(dll_crt0_1): Move sigthread lock initialization to earlier in startup.
	* exceptions.cc (interrupt_on_return): Remove previous kludgy attempt to detect
	an invalid frame.
	(call_handler): Eliminate inner for loop.  Grab signal critical section lock
	where appropriate.
	* sigproc.cc (proc_subproc): Restore uid setting.
	* sigproc.h (sigthread): Reinstitute sigthread lock as a critical section.
	(sigframe): Grab the sigthread lock before clearing frame to avoid having the
	signal thread use an invalid frame.
