main: Add missing locale.h include
The include is present in all other binaries in utils/.
This was originally part of !41 (merged), but @hadess mentioned that
It's already included via
#include <glib/gi18n.h>
so the include isn't missing.
It turns out that glib/gi18n.h
itself does not contain the locale.h
include. In fact, locale.h
only appears in glibc's libintl.h
(which is itself included by glib/gi18n.h
), guarded by the __OPTIMIZE__
macro:
/* Optimized version of the function above. */
#if defined __OPTIMIZE__ && !defined __cplusplus
/* ... */
/* We need LC_MESSAGES for `dgettext'. */
# include <locale.h>
Since __OPTIMIZE__
is not set in every build configuration, we shouldn't depend on this behavior – when all that's needed to fix it is just a single #include
.
Thanks a lot.
