35 # GMock uses tuples extensively, and MSVC bundles a tuple library that
36 # is not compatible with the standard. r675 of googletest works around
37 # this properly, but that's not in GMock 1.7.0. That logic is
38 # duplicated here. See
39 # https://code.google.com/p/googletest/source/detail?r=675#, but note
40 # that its summary does not represent its code correctly.
42 # This function should be called to get the compile definitions
43 # suitable for working around MSVC to compile GMock, if any.
