somewhere.

+ * int version = VERSION_V(2);
+ * const char *strversion = VERSION_V("1.2.3");
+ * struct { int major, minor; } majmin = VERSION_V({2, 0});

+ * And now all places you set a version number can be easily found with grep.
+ *
+ * The macro doesn't care about the actual value, so it'll take strings, etc.
