I'm moving my ham radio server up to 64-bit Fedora 18.  So I'm fixing 
issues as I hit them.

This is against fbbsrc.705e.  When compiled for 64 bits, the code was 
corrupting all my 32-bit data files.
I think this is right, that the binary data files should be the same 
between 32 and 64 bit compiles.

After applying this patch, I see my user names and messages correctly 
after copying data from my old 32-bit install to a new 64-bit install.

I haven't made any patches in awhile so if anything is wrong let me know.
