Cleaned up warnings about unsigned types, unused variables, and declarations. Explicitly declare char as signed for cases when compiling with -funsigned-char. Fixed strict-aliasing issues in IPAddress.h. Fixed array overrun where EXTERNAL_NUM_INTERRUPTS was defined too small.
Local variables can't be declared with PROGMEM and don't need to be when pointing to a PROGMEM address.
This resolves issue arduino#1356 and add the ability for the Arduino IDE to detect the amount of RAM allocated to a sketch and compare that to the available RAM on each board. If RAM is more than 90% full, it will fail on building since there is not enough free RAM for the heap and stack to use.

I've migrated all changes to the ide-1.5.x branch and created #1399 for them. |
