.c files generated with yacc(1) fail to compile under CFLAGS= -Wstrict-prototypes when no -ansi is specified. Fix: The patch below makes it happy with either '-Wstrict-prototypes' and '-Wstrict-prototypes -ansi' and '-Wstrict-prototypes -ansi -pedantic' How-To-Repeat: --- Makefile --- CC = gcc CFLAGS = -Wstrict-prototypes SRCS = a.y PROG = a NOMAN = yes NOOBJ = yes .include <bsd.prog.mk> --- a.y --- %{ void yyerror(const char *s) {} int yylex(void) {} %} %% stmt : ; %% int main(void) { return 0; } --- end --- this produces when compiling: a.c:14: warning: function declaration isn't a prototype a.c:99: warning: function declaration isn't a prototype
