+Subject: [PATCH] bltin: fix timescmd with C23
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+With C23 and LTO, we get the following warning (or error if promoted to such):
+```
+src/builtins.c:28:5: error: type of ‘timescmd’ does not match original declaration [-Werror=lto-type-mismatch]
+   28 | int timescmd(int, char **);
+      |     ^
+src/bltin/times.c:15:5: note: type mismatch in parameter 1
+src/bltin/times.c:15:5: note: type ‘void’ should match type ‘int’
+```
+
+Make the two consistent. This didn't show up before because pre-C23
+had unprototyped functions.
