needs space before the ( -- comes up three times here

don't you want to use tprintf ?

same here

need to unwrap this:
  if (tag)
    {
      printf (tag);
      tag = NULL;
    }

these macro bodies are indented by one space when they should start at two

same here

same here

and here

space before the (

space before the ( -- see int2float

same here

comes up a few times here w/ MULADD & GS

and here w/ MULSUB & GS & MULACC
