I had used them the first time, but then removed them because
I thought there would be no way to pass an argument containing
a comma through the C89 preprocessor.

Actually, there's:

  #define foo ,
  xresize(struct foo, f, 10);

...but how could one possibly abuse this to generate code
that actually compiles?
