After researching the problem on the internet I found some reports that
indicated that this file was too large in some environments.

I attempted to reduce the size by removing some includes from rs6000.md:

This allowed insn-attrtab.c to compile, however the build failed on the very

I also tried the latest 4.3 snapshot with the same results.

GCC 4.2.4 bootstrap is successful on this host.
