I've added no. 2, 3 and 4 to the testsuite.  Our test harness doesn't seem
capable of accomodating multi-locus error messages, so no. 5 and 6 will
require some TCL work unfortunately.

(annotating testcases to fail is easy, outside of above problems: say "{dg-do
compile }" and then, on the same line that should give an error, say {
dg-error "some part of error message that should be matched" "human-readable
name for the error" } where the two strings are not required.)
