Another problem is in the fact that value references in @include commands are
expanded only from texinfo version 4.4 and newer. This means, that version 4.4
or higher of texinfo is _required_ to build the documentation.

Interested people could check texinfo's ChangeLog.46 for the changeset:

2003-01-12    <karl@gnu.org>

	...

	* makeinfo/cmds.c (handle_include): call text_expansion on the
	filename, so @value constructs are expanded.

	* doc/texinfo.txi (verbatiminclude, Using Include Files): mention
	@value expansion.

	...

Using texinfo 4.2, bootstrap fails with:

if [ xinfo = xinfo ]; then \
        makeinfo --split-size=5000000 --split-size=5000000 --no-split -I . -I
../../gcc-svn/trunk/gcc/doc \
                -I ../../gcc-svn/trunk/gcc/doc/include -o doc/gcc.info
../../gcc-svn/trunk/gcc/doc/gcc.texi; \
fi
../../gcc-svn/trunk/gcc/doc/invoke.texi:1057: @include
`@value{srcdir}/../libiberty/at-file.texi': No such file or directory.
makeinfo: Removing output file `doc/gcc.info' due to errors; use --force to
preserve.
gmake[2]: *** [doc/gcc.info] Error 2

Attached (untested) diff should update the required version of texinfo.
