I think Ruby has started to support large files since 1.6.8.
As far as I understand large files can be supported in two ways on
Solaris:

 1) by making an application a 64-bit application

 2) by enabling large file support by setting _FILE_OFFSET_BITS = 64.
    The "configure" step of Ruby does this automatically on Solaris.

I assume that 1) was never an option for Ruby (e.g. pointer would
be 64-bit then). I also think that the #error line in "procfs.h"
just states the fact that you pay a price if you choose 2) above.

The little things I know about this I learned from "Solaris 7 64-bit
Developer's Guide" (available on Suns web-site). The /proc stuff is
mentioned explicitly there as an issue to think about.

( I hope my description above is consistent with that paper ... )

If you don't need large file support, I guess you could just disable
that and get your /proc stuff working in a "pure 32-bit world".

Does this help ?
