Applied with slight correction in r...... Correction was to place 2 tests in t/configure/25-options_test.t into SKIP blocks when $ENV {PERL5OPT}=-MDevel::Cover. This was necessary because Devel::Cover was gagging on running tests within tests.
Tested in both trunk and reconfigure branch; results in same % Parrot::Config::Generated::PConfig as regular configuration. Should have no impact if you choose not to use one or another variant of the '--test' option to Configure.pl.
