Meanwhile mainframes represent maybe (optimistically( 0.1% of the total 
market for compilers. And for the 99.9% representing everything else, C 
and C++ have maybe a 90% market share (if not more), meaning C and C++ 
are totally dominating when it comes to languages for implementing 
compilers.

Just observing...

(And the same is true if we talk operating systems, except that C++ is 
rather minor.)
