There is no generic copy-of-uapgcc comment, you'll have to see uapgcc

for that. If applicable, there is a CRIS-specific comment. The order

of macro definitions follow the order in the manual. Every section in

the manual (node in the info pages) has an introductory `Node:

<subchapter>' comment. If no macros are defined for a section, only

the section-comment is present. */
