Thanks for the fix. This is in code I'd inherited from Devel::Size 0.72, which was (as far as I know) developed on Win32 systems, so I infer *used* to work. (And I think CPAN testers reports on earlier versions showed that it used to build). I was aware that there was now a problem, but didn't have any real idea what the fix was. Sorry for the long delay in responding. I've now uploaded a development version, and intend to upload 0.78 in the next few days, once I get a CPAN testers report from a Win32 system, and no obvious regressions on anything else. (I'm aware that 5.17.1 and 5.17.2 have problems, but as they are development releases of perl 5, I'm not going to hold out until I've figured out what the cause of the problems there is) Nicholas Clark.
