   There is no generic copy-of-uapgcc comment, you'll have to see uapgcc
30
   for that.  If applicable, there is a CRIS-specific comment.  The order
31
   of macro definitions follow the order in the manual.  Every section in
32
   the manual (node in the info pages) has an introductory `Node:

   <subchapter>' comment.  If no macros are defined for a section, only
34
   the section-comment is present.  */
