+Subject: [PATCH] testtyp.c: Use proper prototype for main function
+
+Newer compilers like clang-15+ will complain about the prototype
+vigorously, and the test will end up failing for this reason instead of
+real check it should be failing/passing for.
+
+Fixes
+testint.c:11:1: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]
+main() {
+^
+int
+1 error generated.
