#2642: Toolkit Fails to Compile on Sawtooth (Idaho National Lab)

Comment (by Roland Haas):

This is the sympton caused by using an outdated stdc++ template [library. In](http://library.In) you fix you are basically re-introducing the compatibility hacks (more or less) that we have just removed from Cactus. A better fix for the compilation failure is to make sure that icpc uses a new enough g++ (and its STL library) by passing a `-gxx-name` option and the path to a new enough g++.

If on the other hand you really want an isnan that persists even when -Ofast is used (though you are defeating the Ofast purpose in that case and with Ofast there just may not be any NaN produce in a consitent way to begin with) you could use your change. But it addresses a different issue than the compilation failure I think.
