Hidden warning during compilation

[lestofante]

in brach 1.5.x avr-gcc is called passing argument -w, that hide all warning.
This is very bad as wanings help to find error in the code, especially if it is written by someone new to coding and the magic of pointers.

please, at least give a flag in preferencies to remove the evil -w flag.

thank you

Agreed, this has annoyed me for a while too. It seems that the core is not warning-free, so perhaps that's why the flag was introduced, but then at the least it should only be applied to the core and not the sketch and libraries. Even better, we should make the core warning free and compile everything without -w.

we (italian community) are working in this direction, warning-free for
current-arduino AND current-released avr-gcc (3.4.3). I'll pull-request
when the work will be over AND tested
