[Bug c++/39089] New: -Wconversion is buggy with bitwise operators

[oleg dot smolsky at riverbed dot com]

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...
