gcc42 fails to build with texinfo 4.11

[Rainer Müller]

Hi,

Since the texinfo port was updated to 4.11, gcc42 fails to build. This
is an upstream issue, I found some information here:
http://gcc.gnu.org/ml/gcc-patches/2007-09/msg01271.html

Error log:
| [...]
| Doing info in libiberty

/opt/local/var/macports/build/_Users_Raim_Dev_macports_trunk_dports_lang_gcc42/work/gcc-4.2.1/missing
makeinfo --split-size=5000000 -I../../gcc-4.2.1/libiberty
../../gcc-4.2.1/libiberty/libiberty.texi
| WARNING: `makeinfo' is missing on your system.  You should only need it if

|          indirectly affecting the aspect of the manual.  The spurious
|          call might also be the consequence of using a buggy `make' (AIX,
|          DU, IRIX).  You might want to install the `Texinfo' package or
|          the `GNU make' package.  Grab either from any GNU archive site.

What should we do about this issue? Wait for 4.2.2 where this seems to
get fixed? Downgrade texinfo to 4.9 and hold back the upgrade? Or patch
the configure/build scripts to accept the new version?

This may affect other ports, too.
