Detecting an undeclared identifier before the compiler

I'm working on a multi-platform codebase, and on one of the platforms, sprintf_s isn't available, but snprintf does exist, so in this case the solution is to have the line

#define sprintf_s snprintf

However, I'd like to either automatically revert this (or throw a compile time error so I can do it manually) should the platform implement sprintf_s.

I've found multiple questions here to detect if a class has a member function defined (or an overload exists of a stream operator), but none for a function like sprintf_s.

(I'd rather not use anything experimental, but if std::experimental::is_detected is the only solution so be it).

The ideal solution looks something like

if !sprintf exists
    #define sprintf_s snprintf

but something like the following would also be acceptable

static_assert(!sprintf_s_exists, "sprintf_s is now defined");
