in thread length of pack 'J' and Win64/Win32 C data type model, pointer length, DWORD_PTR

Haven't yet come across a Win32 (32-bit) perl built with 64-bit integer support - but yes, with the right hacks applied to the perl source, it should be possible to build such a perl.

Cheers,
Rob

    I'd hardly call a configuration option a hack. (I realise the procedure is different on Windows, but elsewhere it simply involves passing -Duse64bitall to Configure.)

      Neither would I. (I chose the word carefully and deliberately.)

      The makefiles that ship with the source don't accommodate the option of building 64-bit integers into a 32-bit perl ... afaik you'd have to do some non-trivial hacking.

        Absolutely. I tried it once.

        We complain about the current 2106 warnings that the "successful build produces, you should see what happens when you try adding a few __int64 #defines/typedefs to the equation. Working what to change is impossible.

        Don't ya just love theoreticians :)
