// Test for message: do-while macro '%.*s' ends with semicolon [385]

/*
 * A function-like macro that consists of a do-while statement is intended to
 * expand to a single statement, but without the trailing semicolon, as the
 * semicolon is already provided by the calling site. When the macro expansion
 * ends with a semicolon, there are two semicolons, which can lead to syntax
 * errors.
