>Description:
Test 18_support/numeric_limits.cc execution now fails on cygwin with assertion "extrema_min == limits_min" failed.  Stepping through with the debugger shows it is failing for the long double case.

If I change the test to use the long double specialization that FreeBSD uses then the test passes, so things can't be too bad.

I am unsure if this is best fix, but it may be good enough.
