I just found a workaround: fgetpos and fsetpos take __int64 positions and 
do not require msvcr90.dll.  I can use these instead of fseek/ftell.

Digging into the Qt sources, it looks like _fseeki64 and _ftelli64 are used 
for VC++ while fseeko64 and ftello64 are used for g++.

Preliminary tests indicate that either of the above work for my big files.

All my troubles go back to searching for fseek in MinGW stdio.h and finding 
_fseeki64 followed by some win9x-specific stuff.  If I'd just searched a 
little further, I would have found fseeko64.

Thanks.
