I think you know my position already.  I think it is reasonable to
require that tm-, nm-, and xm- headers to include any headers that
contain definitions, declarations, etc. that are needed.  

As a result, this lifts the requirement that all modules must include
all header files that any (of the zillion) tm-, nm-, or xm- header
depends on.
