Hi,
This patch skips pr80341.c for targets with int size less than 32 bits.
The assertion in the testcase holds only if sizeof(int) > sizeof(short),
which isn't true for smaller int size targets like the avr.
Specifically, after integer promotion, the "usual arithmetic
conversion" of the unsigned short to signed int doesn't occur, and
this causes the test to fail.
Committed as obvious.
Regards
Senthil
