The build failure is a check for the 'uoff_t' definition, which
does indeed seem related to the 64-bit time_t, but would in theory
cause problems without that as well.
There is upstream code specifically to handle different definitions
for off_t here, so I would assume that they are trying to support
32-bit still. I couldn't easily see what exactly went wrong, but
it's probably a oneline fix.
