While this statement is absolutely true about C, which has never had any
facilities for interfacing with other languages, it takes only one to tango
here, and other languages *do* concern themselves with multi-language
programming. For example in Ada a required feature is
pragma Import (C, name-of-function-in-Ada, name-of-function-in-C);
and the compiler is *required* to make sure that the calling sequence is
C-compatible.
Actually in the case of GNAT, we don't even need to use pragma Import, since
the default calling convention is precisely compatible with C anyway.
