Bug: turn on SD_FAST_XFER_AKTIV and compilation fails if PID is
enabled. Fix: If SD_FAST_XFER_AKTIV is defined, fast_xfer() only declares g_heater_pwm_val if PIDTEMP is defined, but later assigns g_heater_pwm_val=0 regardless whether PIDTEMP is defined or not. If PIDTEMP is undefined, g_heater_pwm_val is undeclared at compile time and generates the appropriate error. I solved by not using g_heater_pwm_val if PIDTEMP is undefined (and therefor undeclared.) Also, the extern declaration was as an int, when g_heater_pwm_val is defined as a volatile unsigned char. This caused a duplicate declaration error, which was solved by changing the declaration in fast_xfer() to match the definition. I didn't dig deeper to try to understand if the mismatch was intentional or test operation other than verify the compile errors no longer occur.
