	If you click on the project in solution explorer, then press F4, the properties window should appear. Towards the bottom there will be the Micro General section, and this option can be added in the Extra Flags option.

	the good section is : "Extra C.elf flags" ; thank you this parameter "-mrelax" allows programming above 128kb for the atmega2560 under Arduino 1.0.x
