That would seem like a system library problem in that it doesn't
define off64_t through stdio.h. What distro are you compiling on?
Also, if you set _GNU_SOURCE, does it then compile? e.g. see
m4/package_libcdev.m4 for how to test whether code compiles under
certain defines.
If it does compile with _GNU_SOURCE being set, then all that needs
to be is to update the autoconf rule.
Cheers,
Dave.
