At this point, I'd rather just get some documentation on the format and
write a small C program to convert it to plain text (just a basic
transaction report of some sort).  Trying to build an old version of
GnuCash is probably going to be a bear (rebuilding xacc 1.0.8 was
'interesting').  I don't really want to interact with the data -- at
this point it is dead and frozen.  I have a gnucash (1.8.8) rpm for
RH7.3, which suggests that GnuCash 1.6 will be very old and would likely
be hard to build at this point (and I certainly don't want to clobber
the current installed version of GnuCash by installing an old RPM).
