Hi Paul,
But there is no implementation for native Windows!
Cygwin does it by use of the PDH functions [1], plus some custom
logic to get the averages right. But 'make' needs only the first number,
therefore it would be sufficient to provide the _current_ load instead
of an average, right? In this case, it could probably be done with
20 lines of code according to [1].

The proper condition for testing for a native Windows platform is
#if defined _WIN32 && ! defined __CYGWIN__
