g++ 4.3.3 emits warnings for every statement in the following function when the
code is built this way:
..../gcc43/bin/g++ -c -Wall -Wconversion test.cpp
void func(unsigned char a, unsigned char b, unsigned char *out)
{
*out = a | b;
*out = out[0] & 0x20;
out[0] &= 0x20;
}
I'd expect bitwise operators to see/preserve argument widths...
