It seems like two bugs in gcc:

The first bug is that one use is not removed; the second bug is that it
is not detected and the error does not come up until linking.

Please give me offlist the following information so that I can try to
reproduce it and submit it to the GCC bugzilla site:

1) preprocessed source code.  Run this

   make clean
   make CFLAGS="--save-temps -O2 -g" usage.o

and send the usage.i and usage.s files.

2) Exact compiler version that you're using, i.e. the output of "gcc

3) Output of "./config.guess" from the m4 build directory.
