2004-02-13* Makefile.in (clean): Remove sigfe.s.Christopher Faylor
(sigfe.s): Ensure that sigfe.s will be regenerated if it does not exist. * dll_init.cc (dll_dllcrt0): Simplify initializing tests. * exceptions.cc (setup_handler): Detect when stub caller is either spinning or has acquired the lock after being suspended to avoid windows problems with suspending a win32 API call. * cygtls.h (_cygtls::spinning): Declare new element. * gendef: Remove unused _siglist_index and _siglist declaration.
