Arduino 1.89 Teensyduino 1.46 generates warnings in NXP_SDHC.cpp here are a few -

[RichardFerraro]

I don't want to muck around in libraries, especially this one. Here are a few warnings. Any suggestions?

C:\Arduino\hardware\teensy\avr\libraries\SD\utility\NXP_SDHC.cpp:1180:12: warning: 'int SDHC_CMD12_StopTransfer()' defined but not used [-Wunused-function]

static int SDHC_CMD12_StopTransfer(void)

^

Where is that file " NXP_SDHC.cpp " from? Not found on my system from TeensyDuino or other libraries I have?
