Subject: [PATCH] Fix missing return statements that are seen with
-Werror=return-type.
Error example:
Code:
#include <locale.h>
int main () {
/* If it's not defined as a macro, try to use as a symbol */
#ifndef LC_MESSAGES
LC_MESSAGES;
#endif
}
Compiler stdout:
Compiler stderr:
In file included from /usr/include/locale.h:25,
from /tmp/tmpep_i4iwg/testfile.c:2:
/usr/include/features.h:382:4: warning: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Wcpp]
382 | # warning _FORTIFY_SOURCE requires compiling with optimization (-O)
| ^~~~~~~
/tmp/tmpep_i4iwg/testfile.c: In function 'main':
/tmp/tmpep_i4iwg/testfile.c:8:9: error: control reaches end of non-void function [-Werror=return-type]
8 | }
| ^
cc1: some warnings being treated as errors
Upstream-Status: Backport
