* defines.h (FLUSH_REGISTER_WINDOWS): Make the flushw call an
inline function instead so it can be used as an expression.
* eval.c (EXEC_TAG, THREAD_SAVE_CONTEXT): Consistently call
FLUSH_REGISTER_WINDOWS before calling setjmp(). (I suspect that
every setjmp() implementation should take care of register
windows, though)
