[Doxygen-users] external references (patch)

[joe b. <be...@mc...>]

Recently, I've been doing some work to integrate documentation from various 
subprojects using doxygen's tag file mechanism. I've run into a couple of
limitations:

- Can not link to @anchors in the main page on external packages.
- All external modules and pages are linked to or appended (even the TODO
  page, etc), even when EXTRACT_ALL is set to NO.

I've attached a patch which (I think) fixes these problems. This patch is 
made against the 1.2.8 release.
