    You know the story: Ada was a submission to a public call from the
US army. But the language was public. I don't know how long it took to
build a reliable compiler for the army, because it may have been secret.
But, for the public, it took many years and was buggy, which prevented
its adoption. When I learnt it, it was already well established, not
only in military applications, but in almost every application where
human life is at stake, like public transportation: automated metro, air
traffic management. In the mean time, C++ was born and grown up, with
some of the features invented in Ada, but with all the weak points of C
and a very steep learning curve, while Ada is rather easy to learn. I
had the chance to attend a one-week lecture as a bootstrap; then the
documentation found on the Internet was enough.

    I only kew two versions of Ada compilers, the one of Adacore, and
Gnat, which are very close. It seems Kevin Chadwick is in better sync
than me. I wrote Ada programs during around 10 years and stopped 9 years
ago because I retired and had no personnal project.
