I would like to know whether there is any difference between
the macro

#define FOO()

Is that even allowed under c89?
If so, chapter and verse please.

Huh? Why not? Ever head of systems where getchar() is a macro?

Look up chapter and verse yourself if you think it's not allowed.
The grammar is something like
# define identifier(identifier-list<opt>) replacement-list new-line
Note the <opt> (optional).
