I don't want to have the huge argument again that we had when this
went in, but I'll reiterate what I said at the time: This mechanism
should be removed no earlier than when there is a released stable
version of Debian GNU/Linux for which GCC 3.2 or later is the default
compiler. Realistically speaking, that means sometime in mid-2004.
That is also the earliest time at which features of GNU Ada present
only in GCC 3.2 can be used in GNAT.
But the problem is that the $(ADAC) mechanism basically *doesn't
work*. In general, you can't compile the Ada sources with a different
version of GCC from the C files due to the potential for incompatible
exception handling. Nearly all of the build problems with Ada have been
due to this.
