[MPlayer-dev-eng] [PATCH] Support large files (>2GiB) on mingw32

[Zuxy Meng]

Hi,

For some reason MinGW provides off64_t, lseek64, fseeko64 and ftello64
instead of FILE_OFFSET_BITS dependent off_t, lseek, fseeko and ftello.
Hence the patch. Tested with a 2.3GB avi file and it worked OK: file
length were reported correctly and file seeking became usable.

BTW I don't know the situation for cygwin so correct the patch if
cygwin doesn't support large files either.
