------- Comment #2 from pinskia at gcc dot gnu dot org  2006-03-31 19:11 -------
Confirmed, a litte more reduced testcase:
typedef unsigned long long U64;
typedef unsigned short U16;
typedef unsigned char U8;

U16 m_rh;
U8 m_gN_eQ;

void f()
{
  U16 m_;

  m_gN_eQ = ((m_rh) ? 0x1ULL
             : (U64)(m_ != 0x3fff))
    == 0xffffffffffULL;
}
