 * testcase:   => driver/recomp002/recomp002


Comment:

 Please tell me this is indeed a bug.

 For a testsuite testcase, append the following two lines to
 `testsuite/tests/driver/recomp002/Makefile`.
 {{{
         touch W.hs
         '$(TEST_HC)' $(TEST_HC_OPTS_NO_RECOMP) --make Q.hs
 }}}

 Only `W.hs` should get recompiled, not `W.hs-boot`.
