+Subject: [PATCH] Define _CONST_X_STRING when including Xaw & Xt headers
+
+Fixes build when building against libXaw 1.0.16 since
+xorg/lib/libxaw@d0fcbd97 changed the definition of XawListChange
+in <X11/Xaw/List.h> from _Xconst char * to String *, where
+String is defined as const if _CONST_X_STRING is defined.
+
+This also clears up 105 of the 162 -Wdiscarded-qualifiers warnings.
+
+Closes: #16
+Fixes: bccb777 ("Fix -Wincompatible-pointer-types warning from gcc (issue #15)")
