这段代码块（来自PEP 3109）的向后（尽可能是2.6）兼容语法是什么：

try:
   self.spawn(pp_args)

   raise CompileError from msg

这是在Python 2.x中最接近的写法：

try:
   self.spawn(pp_args)
except DistutilsExecError as msg:
    print "DistutilsExecError : " + str(DistutilsExecError(msg))
    print
    print "The above exception was the direct cause of the following exception:"
    raise CompileError
