I couldn't try with the testsuite due to an unrelated bug with fixincludes (??), but the equivalent C testcase does indeed fail with the same error, as it should. I understand the idea of bulding with --prefix, it's just that I've had mixed success using it wiht mpfr/gmp. Especially, when the system administrator installed them locally behind my back. I'll give it a try, hopefully later today. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30816
