a62f9d1ace (test-path-utils: offer to run a protectNTFS/protectHFS benchmark, 2019-09-04) add a tool for testing that uses a double variable to keep track of time but prints them with "%lf".
while correct for newer C standards, it is not defined in C89 and it is not needed, since both float and double will be promoted to double by printf and should therefore use "%f"; change it accordingly.
