A related but slightly different problem was exposed by a testcase from Ian
Taylor. The message with the testcase is here:
http://gcc.gnu.org/ml/gcc/2004-06/msg01827.html
My analysis is here:
http://gcc.gnu.org/ml/gcc/2004-06/msg01913.html
Briefly, expand_builtin returns a value even when the ignore parameter is true.
This confuses other code.
