Another possibility is to make each such variable 'static' if it's OK to 
make it static, and to precede every other variable declaration like this:

int foo;

with a declaration like this:

extern int foo;

I do this sort of thing in code that's not a test case, as I find it 
helpful to put the extern declaration into a .h file so that it's tested 
for compatibility when other modules use it.

For test cases this is more a judgment call, but I prefer doing either 
the above or adjusting the warning flags, to ignoring warnings, as the 
other warnings can be useful at time.
