Your most immediate problem is that you're running
gcc-4.8.1/gcc/configure when you should be running gcc-4.8.1/configure.
^^^
The configure script inside the gcc subdirectory ONLY configures the
compiler itself, it doesn't know about all the other extra stuff.
That's why it doesn't recognize those extra configure flags.
ah.. I will try that right away.. I read somewhere that you must use
gcc-4.8.1/configure if you got gcc via svn, and gcc-4.8.1/gcc/configure
otherwise..
