MCUfriend TFT LCD pin re-assignment

I did un-comment this line

#define USE_MEGA_8BIT_PROTOSHIELD in mcufriend.special.h

and

#define USE_SPECIAL //check for custom drivers

but I keep getting this warning

(in the pic)

Can you please inform me on what might be the cause of this problem and could you propose a solution?

a brief explanation would be much appreciated.

I would love to use the shield as it was intended to be used more than anything in this world ,but
the pin problem is killing both my efforts and me spirits.
