Hello, Stephen,
Very strange. The "static" keyword does not mean anything here?
Easy enough to use different symbols in the two different files,
but this situation is not so good for information hiding.
Happy to update rcuperf.c to use a different name, but in the
immortal words of MSDOS, "Are you sure?" :-)
Thanx, Paul
