Unknown CPU given in --with-tune=athlon64-sse3.

[Felyza Wishbringer]

Trying to build trunk. Having an issue with "Unknown CPU given in 
--with-tune=athlon64-sse3."

My configure script is:
cd build;../gcc-4.5/configure --prefix=/opt/gcc-4.5 --enable-lto 
--program-suffix=-4.5 --with-system-zlib --enable-__cxa_atexit 
--with-tune=athlon64-sse3

I'm using the page found at 
http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html as 
reference, which lists, "//k8-sse3, opteron-sse3, athlon64-sse3/"/ as a 
valid option step between the k8 and barcelona lines. /
//
/From trunk/gcc/config.gcc:/
/                echo "Unsupported CPU used in --with-cpu=$with_cpu, 
supported values:" 1>&2/
/                echo "generic atom core2 nocona x86-64 amdfam10 
barcelona k8 opteron athlon64 athlon-fx" 1>&2/
//
No where in config.gcc am I finding mention of 'sse3'.

/Is the lack of the sse3 models an oversight, or intended?//
