The fast-fixincludes system now, to the best of our collective belief,
correctly implements exactly the same functionality as the previous
fixincludes/fixinc.* shell scripts. On most systems where many fixes
are required, this is accomplished by putting most of the functionality
into a binary executable. On systems that had dedicated fixinc.* shell
scripts, those scripts are still used by default until they can be
converted.

THEORY OF OPERATION
See also: http://autogen.freeservers.com
The set of fixes required was distilled down to just the data required
to specify what needed to happen for each fix. Those data were edited
into a new file named gcc/fixinc/inclhack.def. A program called
AutoGen (http://autogen.freeservers.com) uses these definitions to
instantiate several different templates (gcc/fixinc/*.tpl) that then
produces a fixincludes replacement shell script (inclhack.sh), a
replacement binary program (fixincl.x) and a script to drive the
binary fixincl.sh).
THEORY OF OPS
inclhack.def contains a list of potential fixes to be applied to the
system headers. This file is processed by autogen to make both a
shell script and a binary to apply those fixes to your headers.
If the binary cannot be built, the shell version will be used instead.
If mkfixinc.sh determines that your system needs machine-specific
fixes that have not yet been applied to inclhack.def, it will install
and use the current fixinc.* for that system instead.
If there is no special purpose script, then mkfixinc.sh will try to
compile, link and test execute the binary version. If it cannot be
successfully built, the shell version will be used instead. If
mkfixinc.sh determines that your system needs machine-specific fixes
that have not yet been applied to inclhack.def, it will install and
use the current fixinc.* for that system instead.
Usually, the mkfixinc.sh script will be able to detect when
the binary is not runable. If you do have problems, however,
please see "POSSIBLE PROBLEMS" above. Thank you.
