Nik,

This is the sign of a serious configuration error. Patching it there will just hide many other 
problems elsewhere where 64bit integer is needed.

This likely occurs because HAVE_LONG_LONG is not set for some reason when configure 
runs.
If you run configure, I guess the "Checking for 64bit integer type" returns no.

Can you try the following (replace cc by the appropriate (cross)compiler binary) ?
echo 'int main() { long long off=0; }' > conftest.c
cc  -o conftest conftest.c
