As I found while testing a patch for PR ada/37681, all parts of the Ada testsuite lack proper multilib support:
* ada/acats isn't multilib-aware at all (i.e. runs only for the default multilib), and * gnat.dg at least runs the tests for all multilibs, but fails to pass the proper --RTS switch (as noted by Eric Botcazou: http://gcc.gnu.org/ml/gcc-patches/2008-09/msg01998.html) -- Summary: Ada testsuites lack multilib support Product: gcc Version: 4.4.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: testsuite AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ro at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37797
