Hi Steffen,

I have updated the code with your file, this patch, and merged things
back into the trunk. I have also added a few warning fixes, and I think
one of the warnings flagged by GCC was a string comparison bug that used
a s1 == s2 on the pointers, I have made that a 0 == strcmp(s1, s2).

Please check out the latest bogofilter SVN from the trunk.
(Regarding sourceforget.net speed, I hope convert things to Git this year.)

The trunk now seems fine WRT LMDB support on Fedora 28 and FreeBSD 11.2.

Thanks a lot!

Best regards
Matthias
