// from a DLL simpler. All files within this DLL are compiled with the COMPILE_CAMITK_API
// flag defined on the command line. this symbol should not be defined on any project
// that uses this DLL. This way any other project whose source files include this file see
// CAMITK_API functions as being imported from a DLL, whereas this DLL sees symbols
// defined with this macro as being exported.

// The compiler therefore issues a warning.
// The following line is to avoid this particular warning.
// The best would be to ask msvc not only to take the exception into account, but also
// its type. Anyway, I did not find how to do that anywhere, and I am not sure this is
