Undeclared functions in Markup.cpp

[push2312]

Some functions in Markup.cpp file are not declared. Please look into the matter and rectify.

I have build the code using CMake MinGW Makefiles (GUI) and encountering the following error while making the files using mingw32-make, in the Markup.cpp file.
