[Users] CarpetMask compilation errors

[Erik Schnetter]

Can you check that the option -std=gnu++0x is part of CXXFLAGS in your
fedora.cfg?

Did you install gcc46 yourself, or as Fedora package?

It is difficult to debug this remotely. Your problem seems to be that
both the C and the C++ versions of isnan are visible at the same time,
the C version in the global namespace and the C++ version in the std
namespace.

A quick work-around would be to commend out the calls to isnan in this
file. These calls to isnan check only for errors, so you should be
fine.
