Alsys Ada83 is excellent, but is now somewhat out of date (about 6 years
old), will it run for WinXP ?
We never had any need of support in 6 years, but it's no longer supported
nor evolving,
It will have to be replaced someday, at least to take full advantage of
Ada95 features.

Aonix Objectada is excellent for us, except that link time is far too long
for our applications and cannot be used today for dayly development
When the link time is 12mns instead of 20s, and has to be done 10 or 20
times a day, it is a problem.
Will Aonix go on with Ada ? some have doubts

Rational Apex is not bad, but still have some little problems
Will they go on with Ada ? some have doubts too

Gnat (professional or public version) is too far from being suitable for us

So compiler availibility could become critical sooner than you think

From we hear on comp.lang.ada the number of people having our concerns is
everything but high enough ...
The trends towards Ada use depends of who you listen and what kind of
application you develop.

They have been for years and continuously improving.
We have absolutely no reason to worry about that.
If only we had the same situation for Ada compilers, we would have nothing
to worry about.

Have you read my post ?

Now that's done :-)

Have you really read the post entirely ?
