List of all symbols not defined anywhere in GCC

[Zack Weinberg <zack at codesourcery dot com>]

The subject line is not entirely accurate.  What this is, is a list of
all symbols which appear in #if/#ifdef/#ifndef lines somewhere in the
source code, but are not defined anywhere in the source code itself.
All the source files generated from machine descriptions were included
in the process.  There are still a moderate number of false positives,
where the definition comes from configure, the Makefile, the host's
system headers, or the target compiler's predefines.  However, with a
bit of manual checking this should be a useful list for people
interested in pruning down the source tree.  I'll be going on a
chainsaw spree when I get back from Canada at the beginning of June,
but I encourage y'all to beat me to it.
