For something like this:

# 42 "bar.c" 1
# 142 "bar2.c" 1

#warning zappa
# 92 "bar.c" 2
#warning gonzo
# 102 "foo.c" 2
#warning bonkta


we now produce these three warnings:

#1:
In file included from foo.c:3:
In file included from bar.c:42:
bar2.c:143:2: warning: #warning zappa
#warning zappa
 ^

#2:
In file included from foo.c:3:
bar.c:92:2: warning: #warning gonzo
#warning gonzo

foo.c:102:2: warning: #warning bonkta
#warning bonkta

with:

#line 92 "foo.h"
#warning blarg!
#warning blarg!

we now emit:

infrastructure to construct function type.
 - For consistencty, we should probably always use this to construct
   function types, but these are absolutely necessary to ensure that
   we can emit calls to these functions.

a.k.a. Koenig lookup) in C++. Most of the pieces are in place, but for
two:

  - In an unqualified call g(x), even if the name does not refer to
    anything in the current scope, we can still find functions named
    "g" based on ADL. We don't yet have this ability.
  - ADL will need updating for friend functions and templates.
