* acinclude.m4 (ac_cv_func_strncmp_works): Add missing
int return type and parameter list to the definition of main.
Include <stdlib.h> and <string.h> for prototypes.
(ac_cv_c_stack_direction): Add missing
int return type and parameter list to the definitions of
main, find_stack_direction. Include <stdlib.h> for exit
prototype.
