I just uploaded new upstream versions for libbfio and libewf.
Unfortunately, the patches you sent no longer apply, since the code has
changed. I had a quick look, but could not determine what would be the
proper way to fix the build on hurd (and probably kfreebsd).
If you have some time to look at the new version, it would be great so
the package could be fixed before the release.

If I understand correctly, current_working_directory_size is now
uninitialized ? Shouldn't it be set to 0 explicitly ?

The getcwd manpage says that the allocation of memory is an extension to
the POSIX.1-2001 standard, so it seems Linux-specific. Will this cause
any problem on other platforms (I suppose Hurd is OK, but what about
