That's usually called a module system.

// Foo.interface
#define xxx yyy
const int xxx = 3;

// Bar.implementation
uses Foo;

#ifdef xxx
#error "no, xxx is defined in another precompiler translation"
#error "unit, it is not visible here  "
#endif

cout << yyy; // 3

It's ok to use a precompiler in any language, but the language
should not use it as a module system.
