Current compilers just produce warnings about unprototyped definitions, noting that they've been deprecated for decades now, but in C23 mode they're rejected, because they got removed, cf. draft and paper: https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3054.pdf https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2841.htm In short, int whatever(a, b, c) is illegal, and int whatever() is now finally equivalent to int whatever(void); or, to put it another way, when building in C23 mode (which is not /yet/ the default), you get -- >8 -- $ make -j25 make all-recursive make[1]: Entering directory '/home/nabijaczleweli/code/dash' Making all in src make[2]: Entering directory '/home/nabijaczleweli/code/dash/src' CC builtins.def CC mknodes GEN token.h GEN token_vars.h CC mksyntax GEN builtins.h GEN syntax.h GEN nodes.h make all-am make[3]: Entering directory '/home/nabijaczleweli/code/dash/src' CC alias.o CC arith_yacc.o CC arith_yylex.o CC cd.o CC error.o CC eval.o CC exec.o CC expand.o CC histedit.o CC input.o CC jobs.o CC mail.o CC main.o CC memalloc.o CC miscbltin.o CC mystring.o CC options.o CC parser.o CC redir.o CC show.o CC trap.o CC output.o CC system.o CC bltin/printf.o CC bltin/test.o CC bltin/times.o CC var.o CC builtins.o histedit.c:376:16: warning: passing 'const char *' to parameter of type 'char *' discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers] evalstring(s, 0); ^ ./eval.h:54:22: note: passing argument to parameter here int evalstring(char *, int); ^ CC mkinit exec.c:779:18: error: unknown type name 'out' describe_command(out, command, path, verbose) ^ exec.c:779:23: error: unknown type name 'command' describe_command(out, command, path, verbose) ^ exec.c:779:32: error: unknown type name 'path' describe_command(out, command, path, verbose) ^ exec.c:779:38: error: unknown type name 'verbose' describe_command(out, command, path, verbose) ^ exec.c:779:46: error: expected ';' after top level declarator describe_command(out, command, path, verbose) ^ ; exec.c:784:1: error: expected identifier or '(' { ^ exec.c:885:12: error: unknown type name 'argc' commandcmd(argc, argv) ^ exec.c:885:18:options.c error: :unknown type name 'argv'393 :commandcmd(argc, argv)14: ^ error: unknown type name 'value' getoptsreset(value) ^ exec.c:885:23: error: expected ';' after top level declarator commandcmd(argc, argv) ^ ; options.c:393:20: exec.c:888:1: error: error: expected identifier or '(' {expected ';' after top level declarator ^ getoptsreset(value) ^ ; options.c:395:1: error: expected identifier or '(' { ^ 10 errors generated.
