+	* config/avr/avr.h (LONG_LONG_TYPE_SIZE): Changed long long type
+	to support 32-bit -mint8 mode.
+
+	* doc/invoke.texi (-mint8): Added documentation for the -mint8
+	option in the AVR architecture.

+Assume int to be 8 bit integer. This affects the sizes of all types: A
+char will be 1 byte, an int will be 1 byte, an long will be 2 bytes
+and long long will be 4 bytes. Please note that this option does not
+comply to the C standards, but it will provide you with smaller code
+size.
