Are you serious when you say things were easier with Turbo-Pascal?
Certainly no problem with different versions of the validation, there
is no validation... just new versions of the language appearing every
year or so, with incompatibilities (do you remember upgrading from
V3.0 to V4.0? It still hurts!). And will Borland exist for the next
40 years? You'd better hope so, because there is no alternate vendor
for Turbo-Pascal!

There is only one Ada language, and all versions of the ACVC test this
same language; 1.11 has just more tests than 1.10. 
No other language is so strictely controlled, so uniform, so validated
or has so many compilers second sources. It does not mean there is no
risk for the future: it just means that the risks are order of magnitude
lower than with any other language.
