Older version of HP NonStop only have a c89 compiler, newer have a -Wc99lite switch to that, which enables some C99 features and the latest additionally have a c99 compiler. There's no switch to cripple something, it is just a fact that older systems don't have c99 or only limited support for it. A whole series of machines (which is still in use!) cannot get upgraded to anything better than c89.
