Hi Mark,

I've had a look into the test summary of the s390 build-bot and compared 
it with my results:
FAIL: math/test-double
FAIL: math/test-idouble
FAIL: math/test-ifloat
FAIL: math/test-ildouble
=> At least fails with pow(1, SNaN) in test-[i]double are due to gcc Bug 
78857 - S390: Do not use load-and-test floating-point instruction to 
compare against 0.0 as SNaN is converted to QNaN. 
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78857)
=> Unfortunately I don't see the other fails on my Fedora 24 system. Can 
you have a look into the out-files?

FAIL: posix/tst-getaddrinfo4
=> Is this related to your IPv6 setup you've mentioned the last time?

=> You have to install gdb and python-pexpect.
Furthermore for the *attr-printers, you have to build glibc with debug 
information.

libstdc++-static.

Summary of test results:
      5 FAIL
   2499 PASS

Bye.
