+// ISO C++ 14882: 22.1  Locales
+//
+
+//  We don't use the C-locale masks defined in mingw/include/ctype.h
+//  because those masks do not conform to the requirements of 22.2.1.
+//  In particular, a separate 'print' bitmask does not exist (isprint(c)
+//  relies on a combination of flags) and the  '_ALPHA' mask is also a
+//  combination of simple bitmasks.  Thus, we define libstdc++-specific
+//  masks here, based on the generic masks, and the corresponding
+//  classic_table in ctype_noninline.h.
