This is the file that causes the boostrap to fail if --enable-decimal-float is
used as a configuration option on the LRA branch. You need to compile this in
32-bit mode with either -mcpu=power7, -mcpu=power6, or -mhard-dfp to enable the
decimal instructions. I used -m32 -O2 -O3 -mcpu=power6.
The error message is:
