Well, TinyPerl 5.8 says "MSWin32-x86-multi-thread"

and I can confirm that it can open a 7GB file and seek way past the 4GB mark and correctly read from the file using the sysopen, sysseek, and sysread functions.

The 4GB limitation applies to DOS, because the DOS system calls limit the file pointer to 4GB. So, you can't seek past the 4GB mark with programs written for DOS mode. EDIT: Actually, I tested Perl 5.004, and it won't even open the file that is larger than 4GB. But that's ancient technology right there.
