Re: Porting ADA source

Right. The only problem being that you are suddenly into rather 
significantly changing the software. You're repackaging things and 
restructuring things and you've got to try to set up some kind of 
configuration control process to accommodate two builds. If you are 
starting from scratch and you know you have to maintain portability this 
might be a valid approach (though I've seen this get waaaaayyy overblown 
too!)

But the mission is to take code body X and get it from its existing 
platform onto another - not redesign the system. Time spent reorganizing 
the code and setting up a build process does not directly move that 
mission forward. Hence, it would be nice to get some kind of quick and 
dirty fix that doesn't mean spending excessive time reworking the 
existing product. A conditional compilation directive can be that sort 
of fix. Its just that it is viewed dimly as a sub-optimal formal 
technique. Oh well....
