I am pleased to announce that I successfully built couple versions of the Tomato-RT with newest known GCC for MIPSEL platform I've found. These builds are smaller than these compiled with GCC 4.2.4.

Caution! These binaries are for EXTREME stunt men only! Loading this may brick your router and such risk is unfortunately highly possible in this case. I will NOT help you in debricking your router if you do not know how to do that yourself (tftp is recommended solution).
However, if you decide to load that stuff, please report whether it was successful. Thank you!
