Log Message:
xbiff: update to 1.0.5.

This release adds -help & -version command line options.

For those building for 32-bit platforms, it also enables use of the
"large file" APIs so that it can handle mailboxes which exceed 2gb
or which may be stored on a filesystem which uses large inode numbers
not supported by the original 32-bit APIs.

Since this release was generated using the new GNU autoconf 2.72, this
also adds a --enable-year2038 configure flag which may allow a 32-bit
build of xbiff to work with files whose timestamps are later than
January 19, 2038, but this has not been tested.
