| Do we assert for any other C90 features before using them?
As I understand it we do require ISO C90 compiler, but not ISO C90
library. Given that, either
(1) the lack of assertion of ISO C90 library function is a bug; or
(2) we move on assuming ISO C90 library.
If we don't do (2) then failing to assert is not a feature.
