what could this error message be telling me?

code: [select]


in file included /applications/arduino.app/contents/resources/java/hardware/arduino/cores/arduino/wiring_digital.c:27:
/applications/arduino.app/contents/resources/java/hardware/arduino/cores/arduino/digital_write.h:137: error: redefinition of 'atomicwrite'
/applications/arduino.app/contents/resources/java/hardware/arduino/cores/arduino/digital_write.h:137: error: previous definition of 'atomicwrite' here


so saying redefined function on same line ?!?

sometimes feel compiler never friend.

it occurred me while raking leaves, knowing had done before error occurred split code out of wiring.h (it had become more 1/2 of there , files in core pretty small) , bit of change wiring_digital.c , perhaps i'd left unbalanced #if of sort in 1 of 3 files. not seem case; #error messages appended each of these files generate expected error message.
