Bull.

You just need to use a different compiler. Ada /= GNAT!

Janus/Ada 95 shares all generic bodies. That's probably too aggressive,
but it's too expensive to change.

Dan Eilers will tell you that their compiler (ICC) shares generic bodies
(I believe unless pragma Inline is used on the generic).

Many Ada 83 compilers shared generic bodies, include DEC and Rational.
It's harder in Ada 95, but if there was any significant demand,
compilers would have it.
