Andrew,
Thank you. That obvious answer had escaped me.
I'd be happy to have preprocessor/7452 closed as Not A Bug, with your
helpful comments below attached.
Humbly Yours,

The following will work as expected:
#define foo(A) { bar->A() }
foo( methodOfBar );
There is no need for pasting.
The only need for pasting is where you have two identifiers and
you want them to be one identifier.
Thanks,

Andrew,
Thank you for your patient explanation. If I do wish to use the modern
preprocessor, is it possible in any way to have some:
#define foo(A) { bar-> ## A() }
foo( methodOfBar );
Or, without resorting to the "traditional" CPP, can it simply
not be done?
Yours,

It is illegal because you are trying to paste together two
tokens which do not make one token in terms of the C standard.
It has been permanently removed because gcc uses a new
preprocessor, this has been this way since 3.0.
You might get what you expect from using the option -traditional-cpp.
Thanks,

Andrew,
Does the standard allow some way to tack on a method name
(i.e., "is there
another way to do this?"), or has this useful feature simply been
permanently removed?
Also: why is this construct illegal?

What you are doing is illegal according the C standard.
Thanks,
