Dear LLeweLLyn Reese!

The token-pasting operator is only for making tokens - 'foo##bar'
becomes the single token 'foobar' and its result must always
produce a single valid token (or the results are undefined). Your
examples would have pasted a comma onto the begining of a
multichar token, and , is only a valid token by itself.
Ran into the same problem with a construct like this:
this-> ## v
If I change it to
this->x ## v
it works, but that's obviously not what I want. Same problem when
constructing namespace defines like:
mynamespace:: ## v
Is there a way to convince the preprocessor, that I know, what I'm doing and
to accept the result as a vaild token (what it is in C++)? This is with gcc
