...versioning hell, but you end up in #ifdef hell instead.

So, what if we didn...

...endEdit(void *, ParamID);
    tresult restartComponent(void *, int32);
};

#ifdef __cplusplus
extern "C" {
#endif
typedef struct FUnknownVTable...

...C is general littered with #ifdef. Commonplace is the #ifdef __cplusplus and without the preprocessor...

Between them, Simen and Ali have cracked the case. Ali's demonstration that "true" was...

...you're right. It's different than ifdef.

I think version is the closest thing...

This would be correct if `i_am_a_feature` would be always defined, just set...

enum i_am_a_feature = true;

static if(i_am_a_feature) {
   ...
}


enum isn't...
