Analysis: internal_errorf(int, fmt, ...) was only a __dead function if the int argument was non-0, which the Prevent probably was unable to follow. Change all uses of internal_errorf(0, fmt, ...) to internal_warningf(fmt, ...); change the pro- totype of internal_errorf() to internal_errorf(fmt, ...) and all remaining uses remove the non-0 int argument; add __dead to internal_errorf() proto; flesh out guts of internal_errorf() and internal_warningf() into a new local function for optimisation purposes. Some whitespace cleanup and dead code removal (return after internal_errorf(1))
