Many, many counter-examples obviously.

VAX/VMS started out as almost all MACRO-32 and BLISS-32 plus
a bunch of non-native stuff that came in from RSX-11 and ran
in compatibility mode (does that count?).

Server software makes me think IBM - I bet that much of the original
360 software wasn't in C!
