numeric_limits

[Peter Schmid]

I verified that your patch does indeed fix the problem described in PR
libstdc++/7851.

I suggest applying the appended or a similar patch to
libstdc++-v3/testsuite/18_support/numeric_limits.cc, if you like.

Thank you for investigating and fixing the bug. Please close both PRs
libstdc++/7851 and libstdc++/7753.

Hope this helps,

Peter Schmid
