I think "must" is too strong.

Many headers with C++ prototypes in them do not have explicit
'extern "C++"', and instead expect the user to "do the right thing".

However, explicitly specifying the linkage does prevent accidents,
and if you are writing a header for C++ library that you intend to
distribute, explicit linkage specification would be wise.
