AnaGram interim repo (temporary): anagram/support/agsignal.h annotate

annotate anagram/support/agsignal.h @ 6:607e3be6bad8

Adjust to the moving target called the C++ standard. Apparently nowadays it's not allowed to define an explicit copy constructor but not an assignment operator. Consequently, defining the explicit copy constructor in terms of the implicit/automatic assignment operator for general convenience no longer works. Add assignment operators. Caution: not tested with the IBM compiler, but there's no particular reason it shouldn't work.
