Fortunately, D now has a C compiler embedded into it (ImportC). ImportC will compile C11 Standard code, and automatically make the interface to that C code available to D.

This means, if a C library is available, D can use it.

(There are some exceptions. While ImportC will handle C preprocessor metaprogramming just fine, those metaprogramming macros won't be available to the D code, other than simple #define manifest constant declarations.)
