 #ifdef ENABLE_NLS
+// If we put #include <gettext.h> outside of #ifdef ENABLE_NLS and
+// --disable-nls is used, gettext(msgid) is defined as ((const char *)
+// (Msgid)). System header includes libintl.h regardless of
+// --disable-nls. For example, #include <string> will include
+// libintl.h through include chain. Since libintl.h refers gettext and
+// it is defined as non-function form, this causes compile error. User
+// reported gcc-4.2.2 has this problem. But gcc-4.4.5 does not suffer
