/* Checks two conditions for the specified structure:
* 1. That the initializers for the latest version produces the same
* in-memory representation.
* 2. That the function-based initializer supports all versions from 1...n,
* where n is the latest version (often represented by GIT_*_VERSION).
*
* Parameters:
* structname: The name of the structure to test, e.g. git_blame_options.
* structver: The latest version of the specified structure.
* macroinit: The macro that initializes the latest version of the structure.
* funcinitname: The function that initializes the structure. Must have the
* signature "int (structname* instance, int version)".
