36// The following ifdef block is the standard way of creating macros which make exporting
37// from a DLL simpler. All files within this DLL are compiled with the COMPILE_ACTIONVIEWER_API
38// flag defined on the command line. this symbol should not be defined on any project
39// that uses this DLL. This way any other project whose source files include this file see
40// ACTIONVIEWER_API functions as being imported from a DLL, wheras this DLL sees symbols
41// defined with this macro as being exported.

60// It seems that MSVC does not understand exception specification
61// If I understand it well, when _declspec() is used, there is a default
62// nothrow attribute.
63// I did not find the throw attribute. It seems that msvc is therefore ignoring the
64// specification of the type of the exception.
65// The compiler therefore issues a warning.
66// The following line is to avoid this particular warning.
67// The best would be to ask msvc not only to take the exception into account, but also
68// its type. Anyway, I did not find how to do that anywhere, and I am not sure this is
69// possible...
