It would be extremely useful to be able to seek past the 2G limit MS has.

Ticket details:
Although 32-bit Windows has supported operations on files larger than 2GB, since at least WinNT4 and Win98, (and possibly earlier), Microsoft did not introduce the _fseeki64() and _ftelli64() APIs until MSVCR80.DLL, (and subsequently retrofitted it to MSVCRT.DLL, from WinVista onwards); prior to this, random access support in large files was provided through lower level APIs such as _lseeki64(), or native Windows API functions.
As noted in this mailing list query, and this subsequent follow-up thread, it is practicable to emulate the _fseeki64() and _ftelli64() APIs, such that they become available on legacy versions of Windows, which pre-date the formal introduction of these APIs by Microsoft; however, previous efforts to do so may not have been entirely robust. Hopefully, the attached patch will do a better job.
