+==================== work096, patch 12.
+
+Make 'w' the __ibm128 suffix.
+
+In writing code with __ibm128 support, it would be nice if we supported a suffix
+that marked __ibm128 constants.  The preprocessor lexer supports using either
+'q'/'Q' or 'w'/'W' as machine dependent suffixes.  The 'q'/'Q' suffix was
+already taken for __float128 constants, so I added 'w' or 'W' as the suffix for
+the __ibm128 constant.
+
+I went to the file doc/extend.texi to document using a 'w' or 'W' suffix, but it
+appears that we already had documented using 'w'/'W' for __ibm128.  This code
+adds this support to the GCC compiler.
