bug#39553: 28.0.50; ada mode was removed

[Nicholas Savage]

Without speaking to the policy decision of removing ada-mode, I don't seem to 
have the same problem as you do in regards to auto-mode-alist. When I open an 
Ada source file it opens in fundamental mode with no error. Looking through the 
value of auto-mode-alist as well I don't see anything related to Ada, which is 
probably the expected behaviour. I've never dealt with Ada files before, so 
maybe there is a configuration problem on your end?
