Comment:
I committed 09fb4c4, which should suffice to provide robust implementations of
_fseeki64() and _ftelli64() for all WinNT derived platforms. They will also
work on Win9x, but I'm leaving the ticket open for the time being, because, as
I suspected, they will interact badly with fwrite() on these platforms, if the
fwrite() is preceded by an _fseeki64() to an offset beyond the physical end of
file.

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.

Comment:
MinGW uses Microsoft's implementation of sscanf(), so you need to read their
documentation. Note, in particular, this subsidiary reference: this
implementation does not comprehend the hh size modifier, as you use it in your
"%hhu" format specification.
