#define STRINGIFY(s) #s

/* 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)".
