_LARGEFILE_SOURCE=1 and _FILEOFFSET_BITS=64 are enough, just remember
to use size_t and off_t always so system headers can replace it
with the right ones, this is backward compatible, but it's unsupported
on mingw, there is the same problem with compiling mplayer on mingw,
it should be fixed in mingw headers so I bet is better to use this
standard way, it works on almost all unixes and in cygwin.
