The gcc-4.7.3 in lastest nios2 toolchain generated lots of warning on type mismatch. So change typedef of size_t to unsigned int, followed those of arm and mips arch.

I need help on this. I had a similar problem for cmd_sf in 20111214.
This patch works for gcc-4.7.3, but triggers warning for gcc-3.4.6 and gcc-4.1.2.
Before,
gcc-3.4.6 and gcc-4.1.2 got no warning.
gcc-4.7.2 got

After this patch,
gcc-4.7.2 got no warning,
gcc-3.4.6 and gcc-4.1.2 got warning,
