Arduino 32U4 problem

[DSPQPSK]

Hello,
sorry for disturbing you.
Is it possible that there is a problem when using 32U4 processors?

I compile the Soft Serial example with the target Arduino Nano, everything is perfect.
If I now switch to 32U4 based Arduino boards like Leonardo or Micro, then I get the following error:

---

C:\Program Files\Arduino\hardware\arduino\avr\cores\arduino/USBAPI.h:154:16: note: previous declaration as 'Serial_ Serial'

extern Serial_ Serial;

^~~~~~

exit status 1

A similar behavior could be observed if I use the HW Serial example.

Thanks for your support.

The extern HardwareSerial Serial was removed in the new version, so should be fixed now.
