[Bug target/25298] New: Regression: invalid lvalue in assignment

["eweddington at cso dot atmel dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Compiling the source below with avr-gcc 4.0.2 gives an "invalid lvalue in
assignment":

------------------
#include <avr/io.h>

int main(void)
{
    (unsigned char)DDRD |= (unsigned char)(1 << 7);

    return 0;
}
------------------

The same code above builds fine for avr-gcc 3.4.3. The issue has to do with the
typecast of DDRD to unsigned char. If the typecast is removed then it compiles
without error for 4.0.2.
