static tree find_node_with_code	(	tree *	tp,

Find a node with a given code.  This function is used as an argument to
   walk_tree.

static

For each node store in its children nodes that the current node is their
   parent.  This function is used by walk_tree.

static long TB_getline ( )

static

Read up to (and including) a '\n' from STREAM into *LINEPTR
   (and null-terminate it). *LINEPTR is a pointer returned from malloc
   (or NULL), pointing to *N characters of space.  It is realloc'd as
   necessary.  Returns the number of characters read (not including the
   null terminator), or -1 on error or EOF.
   This function comes from sed (and is supposed to be a portable version
   of getline).
