Attempt to build grep-2.5 fails under IRIX-6.5.11f

[Dan Kokron]

I attempted to build grep-2.5 under IRIX-6.5.11f + MIPSpro-7.3.1.2m (also
MIPSpro-7.2.1.2m), but the compile failed with the following messages. 
A google search did not give much help.  Is this a known issue? 
Where might I find a solution?

Thanks
Dan
