[Paraview] CVS head fails to compile on MSVC

[OSHIMA Takuya]

Hi,

I just noticed today's CVS head fails to compile on VS2008 at line 540
of Servers/Common/vtkPVXMLElement.cxx:

      snprintf(temp, 20, "&#x%x;", static_cast<int>(*escape_char));

with error C3861: 'snprintf': identifier not found.

Cheers,
Takuya
