[Bug preprocessor/33907] Empty macro definitions not considered equal

[manu at gcc dot gnu dot org]

------- Comment #17 from manu at gcc dot gnu dot org  2007-11-27 13:57 -------
Can someone suggest a better comment for this? 

 /* Since this diagnostic is mandated by the standard, with -pedantic we
diagnose 
    different parameters spellings even if the macro expansion has no tokens. 
*/ 

The place where the standard requires this would be helpful.
