/* Original info:

Layout of definition function
Members of struct for foo:
  r is 230
  c is 2
  type.t is 6
Members for return type, i.e. foo->type.ref:
  ret->r is 1000
  ret->c is 1
  ret->type.t is 9 (floating point double should be 9)
Members for first argument, i.e. foo->type.ref->next:
  arg1->r is 0
  arg1->c is 0
  arg1->type.t is  is 0 (integer should be 0)
Members for second argument, i.e. foo->type.ref->next->next:
  arg2->r is 0
  arg2->c is 0
  arg2->type.t is 4 (pointer should be 4)
Members for second argument's pointer type, i.e. foo->type.ref->next->next->type.ref:
  arg2pt->r is 0
  arg2pt->c is ffffffff
  arg2pt->type.t is 9 (floating point double should be 9)

Layout of declaration function
Members of struct for foo:
  r is 230
  c is 0
  type.t is 86
Members for return type, i.e. foo->type.ref:
  ret->r is 11000
  ret->c is 1
  ret->type.t is 9 (floating point double should be 9)
Members for first argument, i.e. foo->type.ref->next:
  arg1->r is 0
  arg1->c is 0
  arg1->type.t is  is 0 (integer should be 0)
Members for second argument, i.e. foo->type.ref->next->next:
  arg2->r is 0
  arg2->c is 0
  arg2->type.t is 4 (pointer should be 4)
Members for second argument's pointer type, i.e. foo->type.ref->next->next->type.ref:
  arg2pt->r is 0
  arg2pt->c is ffffffff
  arg2pt->type.t is 9 (floating point double should be 9)

The c and type.t fields need to be updated. The difference with ret->r shows
that the declaration is a prototype, but the definition is not (see the
func_proto bit field of the AttributeDef struct in tcc.h.) Since I want to
make sure that later redefinitions get called out, I will keep this discrepancy
between the two. Note that I might want to update the weak field of the
AttributeDef...
