/* After the first "Node:" comment comes all preprocessor directives and
attached declarations described in the info files, the "Using and
Porting GCC" manual (uapgcc), in the same order as found in the "Target
macros" section in the gcc-2.9x CVS edition of 2000-03-17. FIXME: Not
really, but needs an update anyway.
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. */
