I did now and there are 5 failures as shown below: --snip start-- Running /home/ckumar/ck/gcc295_installation/binutils-2.10.1/gas/testsuite/gas/i386/i386.exp ...

In binutils-2.10.1, that definition was moved into tc.h. I included the definition in as.h of binutils-2.10.1 and built the binutils-2.10.1. The build is successful.
