-    The original intent of this macro was to control whether or not actual
-    exception specifications are emitted, based on how much they impact code
-    size etc. in a specific scenario.  But it ended up always being disabled
-    (except for MSVC, which effectively ignored it even though being enabled),

-    com::sun::star::uno::RuntimeException in com/sun/star/uno/Reference.h), so
-    has officially been demoted to pure documentation now.

-    @deprecated do not use in new code.
