What was your configure command?
Any CFLAGS or CXXFLAGS set in your environment?

We don’t specify -Werror by default.

the -Werror flag comes from gnuradio-core/src/lib/viterbi/Makefile:
INCLUDES = -Wall -Werror

I have this error on ubuntu 8.10. The -Werror flag is there by default,
I never specified it in configure or somewhere else in the system.

This just happened to change when I upgraded from ubuntu 8.04
