The name "foo" is introduced inside a hygienic macro, and should not
be visible outside the macro.  This bug does not manifest for internal
defines within macros.

We are lost, lost.  No name, no business, no Precious, nothing.  Only empty.
Only hungry: yes, we are hungry.  A few little fishes, nassty bony little
fishes, for a poor creature, and they say death.  So wise they are; so just,
so very just.  --Gollum        address@hidden  http://ccil.org/~cowan
