I came across this too.

I just removed the test condition and forced the build. After testing 
it seemed that odbcserver is working fine. I'm actually using it like
that in a production system. I searched the web for more information 
on using odbcserver with 64-bit architecture, but found none.

I haven't done too much code digging myself, but I couldn't see any 
problems. If anyone else have come to other insights, please respond.
