`make info' fails on cc-mode.texi with Texinfo 4.3

[Ralf Angeli]

The build process aborts if `make info' is called with Texinfo 4.3.
Here is the build output:

$ make info
[Please ignore a syntax error on the next line - it is intentional]
/bin/sh.exe: -c: line 1: unexpected EOF while looking for matching `"'
/bin/sh.exe: -c: line 2: syntax error: unexpected end of file
makeinfo --force emacs.texi
makeinfo --force emacs-xtra.texi
makeinfo --force cc-mode.texi
cc-mode.texi:1621: Unknown command `headitem'.
cc-mode.texi:1654: Unknown command `headitem'.
make: *** [../info/ccmode] Error 2

Version information for `makeinfo':

$ makeinfo --version
makeinfo (GNU texinfo) 4.3
[...]

This version comes with current MSYS and does not know @headitem which
was introduced with Texinfo 4.7.

If this counts as a bug in Emacs depends on which versions of Texinfo
the build process should be compatible with, I guess.
