kahrl cafa400fa5 gettext.h: include <locale> before defining the gettext macro (#4452)
Fixes #4446: a syntax error that happens if something else (such as
<iomanip> or <locale> in certain libstdc++ versions) includes
<libintl.h> later, which contains a function declaration for gettext
that gets mangled by the macro.

See the added comment in gettext.h and the discussion in #4446/#4452
for details.
