Well, one concern I would have is making *phobos* dependent on these  
libraries, which may not be needed (or installed).

Note that in recent times, dmd failed to compile any programs Ubuntu  
because of new linking rules.  The solution was to add -lrt to the dmd  
source code that generates the link line.

Is that the same solution for FreeTDS?  What if FreeTDS isn't installed  
(it typically is not)?  What if you don't use the database system, why  
should you have to link against FreeTDS if it's not being used?

I'd much rather have the database subsystem *framework* be a part of  
phobos, and the actual implementations be defined as 3rd party libs.  Just  
 from a practical point of view.
