Teensy 3.1 : multiple compilation errors

[kd-chicago]

Trying to compile TFT_Print_Test

1. error: no declaration matches 'int TFT_ILI9341::drawChar(unsigned int, int, int, int)'
   Cause: drawChar (along with 5 more functions) is defined as int16_t in TFT_ILI9341.h, but is referred as int TFT_ILI9341::drawChar(unsigned int uniCode, int x, int y, int font) in TFT_ILI9341.cpp

2. error:
   '_SFR_IO_ADDR' was not declared in this scope
