Totally agree, which is why I try to do it all in Ada source, with "if 
SSE then..." instead of "#ifdef SSE ..."  The disadvantage of this 
approach is that the code must compile cleanly, even if it will be 
statically eliminated at compile time.

I just haven't found that to be a major hurdle.  I can easily see that 
happening if you are "up against the wall" with a compiler bug.  But 
with GNAT, I have the source, and know how to use it. ;-)
