{all,clean,make,race,run}.bat: use || instead of "if errorlevel 1"
"if errorlevel 1" is and old construct that returns true if the
errorlevel is greater than or equal to 1. There are better alternatives
since Windows NT. For example, the || operator runs the RHS operand if
the preceding command failed, determined by checking that the errorlevel
is different from 0. This approach is more robust -it also works with
negative errorlevels- and is less verbose.
