Ken Brown 262de3ecf0 Cygwin: fix return value of sqrtl on negative infinity 
The return value is now -NaN.

This fixes a bug in the mingw-w64 code that was imported into Cygwin.
The fix is consistent with Posix and Linux.  It is also consistent
with the current mingw-w64 code, with one exception: The mingw-w64
code sets errno to EDOM if the input is -NaN, but this appears to
differ from Posix and Linux.
