I'm looking at this patch now but it'd be good if someone else
(especially Travis and/or Brad) could spend some time reviewing
it too. The goal here is to eventually provide implementations
for these functions (or similar) on all platforms.
Thanks

The output of the program below is different depending on the operating system
it runs on. It should be the same (preferably like that on AIX).
$ cat u.cpp && uname -sr && make u -r && ./u
#include <iostream>
#include <limits>
int main ()
{
std::cout << std::numeric_limits<double>::infinity () << '\n'
<< std::numeric_limits<double>::quiet_NaN () << '\n'
<< std::numeric_limits<double>::signaling_NaN () << '\n';
}
