Correct buggy example of use of __GNUC__ etc.
Clarify $ in identifiers.
* doc/cpp.1: Regenerate.

* class.c (dfs_accumulate_vtbl_inits): Just point to the base we're
sharing a ctor vtable with. Merge code for cases 1 and 2.
(binfo_ctor_vtable): New fn.
(build_vtt_inits, dfs_build_secondary_vptr_vtt_inits): Use it.
From-SVN: r43399

* pt.c (unify): Don't recurse between the POINTER_TYPE and the
OFFSET_TYPE. If we're adding cv-quals, the extra ones would be on
PARM, not ARG.
