help with compiling gcc-4.1.2 on CentOS 6.3 x64

[Han Jiang <oglops@gmail.com>]

Hi all,
i'm compiling gcc 4.1.2 for autodesk maya ( a 3d animation software) ,
and came across these error messages.
i'm following this tutorial
http://docs.autodesk.com/MAYAUL/2013/ENU/Maya-API-Documentation/index.html

Download the gcc 4.1.2 source tar file from http://gcc.gnu.org/install/

Setup directories:
 % mkdir gcc412
 % cd gcc412
 % mkdir gcc-build

Extract the source files:
 % tar zxvf gcc-4.1.2.tar.gz
 % cd gcc-build

Configure the compiler. Run the following all on 1 line:
../gcc-4.1.2/configure --prefix=/opt/gcc412 --program-suffix=412
--enable-shared --enable-threads=posix --enable-checking=release
--with-system-zlib --disable-libunwind-exceptions
--enable-__cxa_atexit

Build the compiler:
 % make -j 2 bootstrap

Everything goes well until this step. i searched the mailing list and
found in 2011 ,Olumide faced with a similar error message,
 http://gcc.gnu.org/ml/gcc-help/2011-01/msg00279.html
but he managed to get it compiled successfully after installing two packages,
"(I had to compiled and install textinfo version 4.9 and install the
latest version ncurses in order to compile texinfo.)"
I have these two packages installed, but still can't compile it.

other preparations i did

yum groupinstall "Development tools"
yum groupinstall "Additional Development"
yum install glibc-devel.i686
yum install libXext-devel


the compiling stops with the following error  messages:

WARNING: `makeinfo' is missing on your system.  You should only need it if
         you modified a `.texi' or `.texinfo' file, or any other file
         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.
