Thanks.

How about between "Types" and "Symbol Tables"?

I don't like this ``sometimes'' thing, it makes one wonder when it
happens and when not.  How about this instead:

  This section describes the stabs support for macro define and
  undefine information, supported on some systems.

These lines need to be shortened to avoid overflowing the page
