you can add -Wall to the gcc command line and it'll let you know if you're
using an uninitialised variable:
willow% gcc -Wall -Werror -c foo.c
foo.c: In function `foo':
foo.c:3: warning: unused variable `bar'
and the -Werror will make that warning an error and refuse to generate
an object file or executable.
