[project @ 2001-05-08 17:33:57 by qrczak]
Fix typo when times() is used.
Move foreign imports inside appropriate #ifdefs.

A small problem remained (besides Win32): For hpux getrusage is defined
here as a macro, and foreign importing a macro relies on compilation
via C. Should be wrapped in a function, but I'm not sure if it's safe
to call it getrusage.
