Of course there is: write your code to use nothing but the target OS 
facilities and Ada. (Yes, I know that Windows uses shared libraries to 
implement the OS interface, but that's not visible to a statically linked 
program.) That was always the requirement at RRS, and any time that we've 
deviated from it we've generally come to regret it.

Statically linked programs are not going to fail because of some upgrade 
outside of botched OS upgrades (which are much less likely than other kinds, 
because most OS vendors are well aware of the havoc that they can cause).

The supposed reasons for using shared libraries rarely hold any water (there 
aren't going to be dozens of nearly identical Ada programs running on a 
single machine at a single time).
