+Define this macro to be a C string representing the format to use
+for constructing the index part of the dump file name on your host machine.
+If you do not define this macro, GCC will use @samp{.%02d.}.  The full
+filename will be the prefix of the assembler file name concatenated with
+the string resulting from applying this format concatenated with a string
+unique to each dump file kind, e.g. @samp{rtl}.
