  11  *     2. That the function-based initializer supports all versions from 1...n,
  12  *        where n is the latest version (often represented by GIT_*_VERSION).
  13  *
  14  * Parameters:
  15  *     structname: The name of the structure to test, e.g. git_blame_options.
  16  *     structver: The latest version of the specified structure.
  17  *     macroinit: The macro that initializes the latest version of the structure.
  18  *     funcinitname: The function that initializes the structure. Must have the
  19  *                   signature "int (structname* instance, int version)".
