make considers gfkp older than f1, is it OK?
(The result is the same without .LOW_RESOLUTION_TIME)
How many digits of the last modification time of the files are
compared to decide to execute a recipe?


.LOW_RESOLUTION_TIME: gfkp f1
gfkp::
        @rm -f gfkp f1
        @touch f1
        @touch gfkp
        @echo 11111
gfkp:: f1
        @echo 222222
