I don't see this build error if I have only libgdbm-dev installed on
debian sid, dbtest just doesn't get built.

But there's no such problem on debian stretch. It seems like that debian
sid moves dbm_(open|close|restore) symbols from package libgdbm to
package libgdbm-compat, which is a new package in sid and not available
in stretch.

So this command will fail on debian stretch (or other earlier releases)
as there's no libgdbm-compat-dev package. Not a big problem, but a bit
annoying, I think.

I'm wondering if we just convert src/dbtest.c to use the gdbm_ functions
instead of the dbm_ ones (and perhaps we can simplify
m4/package_gdbmdev.m4 file too)? Though it's not a trivial replacement..

Thanks,
