| // Tests whether rescanning of a macro replace any macro call in the replacement |
| // text after substitution of parameters by pre-expanded-arguments. This |
| // re-examination may involve the succeeding sequences from the source |
| // file (what a queer thing!). |
| |
| // Note: The tests 27.4 and 27.5 are currently disabled because of Wave's |
| // problem with replacement-list terminating in partial macro expansion. |
