Re: Compile errors: timeout/time.h error

Hello I found this bug in the bootloader of 2560 board

https://code.google.com/p/arduino/issues/detail?id=392

It should be our case. I found in the code in source Marlinmain.cpp a "!!!" in a text. I try to remove it but I am stuck I can't upload cause of the error.
