This is the current bash build available in nekoware.

I built bash 4.1.7 with MIPSpro using the same compiler options as the
current 3.1.16 build and it exhibits the same issue.
After removing optimisation options from CFLAGS the build works so
it seems MIPSpro is miscompiling something when optimisation is turned
on.

I'll let the nekoware guys now that something is fishy with their current
build.
