Michael Brown bc93e8ab41 [util] Avoid compiler warning on gcc 4.6 Commit 196751c ("[build] Enable warnings when building utilities") revealed a previously hidden compiler warning in util/nrv2b.c regarding an out-of-bounds array subscript in the code #if defined(SWD_BEST_OFF) if (s->best_pos[2] == 0) s->best_pos[2] = key + 1; #endif where best_pos[] is defined by #define SWD_BEST_OFF 1 #if defined(SWD_BEST_OFF) unsigned int best_off[ SWD_BEST_OFF ]; unsigned int best_pos[ SWD_BEST_OFF ]; #endif With SWD_BEST_OFF set to 1, it can be proven that all code paths referring to s->best_off[] and s->best_pos[] will never be executed, with the exception of the two lines above. Since these two lines alone can have no effect on execution, we can safely undefine SWD_BEST_OFF. Verified by comparing md5sums of bin/undionly.kpxe before and after the change.
