Linking is irrelevant. If your modules are not derivative works of 
"GPLed Libraries and Programs" (seek the advice of your own legal 
counsel re AFC test), then I suggest that you simply go ahead with 
the CPL or EPL; if somebody dares to come after you claiming GPL 
violation (in court of law, not those empty threats and "opinions" 
the FSF is so fond of), you'll have a good chance to put the entire 
GPL code base into quasi public domain. Google "Open Source 
Licensing: Virus or Virtue?" and "GPL + "copyright misuse"". Show 
the hits to your own legal counsel.
