For some reason (that I haven't yet investigated), with ActivePerl I then get undefined references to `CreateJobObjectA', `SetInformationJobObject', `AssignProcessToJobObject'

Well ... I investigated and investigated ... then investigated a bit more ... and still couldn't see what the problem was.
So I then gave up and posted to the ActiveState users list - and about half an hour later Mark Dootson replied with the explanation and solution.

When this linking problem occurs, we'll find that lib/CORE/win32.h begins with something like: 
#ifndef _WIN32_WINNT
#  define _WIN32_WINNT 0x0400
#endif

[download]
But we need _WIN32_WINNT to be >= 0x0500 - which I achieved by altering the above code to: 
#ifndef _WIN32_WINNT
#  define _WIN32_WINNT 0x0500
#endif

[download]
That then enables the script to run to completion, and I think it also takes care of the '...undefined; assuming extern returning int' warnings with Microsoft compilers.

Cheers,
Rob
