Hi Michael,
This compile error should be fixed now. You should update Paraview to the
latest version and also do a 'git submodule update' to update Xdmf.

Include <string.h> for XdmfSetStringMacro
We need this header for strcmp in the macro implementation. This error
went unnoticed previously because places that used XdmfSetStringMacro
happened to include <string.h> for another reason.
