[Geert Uytterhoeven <geert-Td1EMuHUCqxL1ZNQvxDV9g@public.gmane.org>]

On 32-bit:

execveat.c: In function 'check_execveat_pathmax':
execveat.c:183: warning: format '%lu' expects type 'long unsigned int', but argument 3 has type 'size_t'
execveat.c:187: warning: format '%lu' expects type 'long unsigned int', but argument 2 has type 'size_t'
