GNU assembler version 2.14 (mips-linux) using BFD version 2.14 20030612
That is from ELDK  3.1.1 (binutils 2.14-6), I definitely get the error.

GNU assembler version 2.14.90.0.6 (mips-linux) using BFD version 
2.14.90.0.6 20030820 uClibc
This works, but the warning is present. There's a 3 months difference here.

The warning seems harmless.

We can somewhat revert the changes made, that's the only way it would 
work with that particular version.
Apparently,  .gpword was supposed to work only on local symbols (this 
comes from the MIPSpro tools), but this
was relaxed in later versions of gas. See

Patch to follow.
