FYI: I "accidentally" committed a change to configure.ac that
looks for nan in the std:: namespace. As it worked on my system
before reverting it I'd wait for someone else to scream about
some broken build.

Then I'd move to the NAN macro (or inlined function)

This problem would be much better handled in a ticket, btw...
