The problem was introduced when I build the source tarball using autoconf-2.61. Apparently, _LARGEFILE_SOURCE isn't really needed with the header files shipped with newer versions of glibc, but it breaks when built with glibc-2.3. I have a fix in cvs to work around this by defining _LARGEFILE_SOURCE in libfs/devices.c, but I've been negligent and haven't published jfsutils-1.1.13 yet. Thanks for reporting the problem, and I'm sorry that I put you through so much trouble to track down the problem which I should have fixed with a new release.
