The C99 standard says that real operands aren't converted to complex, but 
as I note in bug 24581, the compiler doesn't expect PLUS_EXPR and 
MULT_EXPR to have arguments of different types, so the front ends might 
need adapting to handle real * complex and real + complex specially.  
Patches welcome, see <http://gcc.gnu.org/contribute.html>.
