'gettext' even might be defined as libintl_gettext. With this exchange, I was aiming for extracting a more useful title for this patch out of you ;-), and I think I accomplished my goal. "Properly" is fairly a useless adverb in the context of a patch title, as it does not tell us why we thought the way in which the updated code works is more "proper". In addition, because no code is perfect, future developers are bound to find something inproperly done in checking for libintl after this patch gets applied. It is better to say the most important thing the change does concisely and concretely. I think autoconf: #include <libintl.h> when checking for gettext() is probably a better title. Together with your originally proposed log message, which we now know explains why this inclusion makes a difference sufficiently to be understandable by an average Git developer, the resulting commit will communicate to our future developers the reason why we thought this was a good change clearly. Thanks.
