Why not gnat Ada in gcc?

[Richard Kenner]

    Is it possible that they lost interest because they don't think
    they're going even playing field with ACT?

No.  They weren't planning on doing GNAT development, but merely
working on integration issues.  They seemed eager to start, and were
encouraged to do so, but the level of interest seemed to be waning.  A
number of people associated with ACT Europe were also associated with
them, so they had an "inside track", but it didn't seem to help.

This is why I view with skepticism the belief that other developers will
somehow appear.
