* module/rnrs/base.scm (error, assert): Define -- they were missing. (assertion-violation): Properly treat a #f `who' argument. * module/rnrs/conditions.scm (condition): Use `assertion-violation' instead of the undefined `raise'. (define-condition-type): Fix for multiple fields. * test-suite/tests/r6rs-conditions.test: Test accessors of a multiple-field condition. Also import `(rnrs base)' to allow stand-alone running of the tests; apparently the `@' references scattered throughout the R6RS modules make the libraries sensitive to their load order -- for instance, trying to load `(rnrs conditions)' before `(rnrs base)' is loaded fails. * module/rnrs/records/inspection.scm: Use `assertion-violation' instead of an explicit `raise'. * module/rnrs/records/syntactic.scm (process-fields): Use `syntax-violation' instead of bogus invocations of `error'.
