That was basically my impression. DEC/Ada83 vs Gnat/Ada95. I don't remember if DEC was in the business of directly selling a Gnat distribution with/without any specific support - but I do remember their sales weenies indicating that this was the upgrade path from Ada83. I basically got the public distribution and had our IT dude install it & it worked fine. When DEC was assimilated I figured Compaq would continue support for whatever DEC did while migrating towards other products, until the last vestiges of DEC withered away and were consigned to the dustbin of history. I figured that the Ada83 compiler would go along for the ride. (pity - it was a really great compiler and one of the very first descent quality Ada implementations.) However, the Gnat library model was really a better idea as was Ada95, so I didn't shed too many tears over it. About the only incompatibility I tripped across in porting the code I was responsible for was a difference of opinion on how to implement discriminated records. It was not hard to find or fix, so the port was mostly painless. It was a real testimony to the portability of Ada - I had Ada code that worked on PC/NT, Sun/Unix and Alpha/VMS and the porting between the three platforms was pretty much just a recompile and go. (Except for systems where we hooked heavily to OS services or file formats I can't recall anything that didn't just recompile & run with no bugs introduced.
