I had this problem too.  The actually error is that g++ is producing
.extern lines for variables actually declared in the same file.  My
solution I found was to either produce the assemble, remove the
spurious .extern's and assemble it myself, or to re-order the source
lines to put the declarations of the variables ahead of the extern's
for them (or something like that, I know that re-ordering the code
solved the problem).

I wish the MIPS assembler would be more forgiving about things like
this, or at least produce a more informative error message.
