[omniORB] another IDL question

[Paul Brannan]

With this interface:

  interface Foo
  {
    void bar(in long factory);
  };

I get this error:

  [pbrannan@zaphod test3]$ omniidl -bcxx Foo.idl
  Foo.idl:3: Syntax error in operation parameters
  omniidl: 1 error.

It seems that the IDL compiler doesn't like the name 'factory'.  Any ideas
why this is happening?

Thanks,

Paul
