While creating a mixture of GPL, BSD, CPL, other similarly licensed 
source files and linking them together seems to not violate user 
freedoms, CPL marked as incompatible by gnu.org is good enough reason to 
say no thanks.
Maybe instead of going in circles, it would be interesting to see if a 
project such as eclipse accepts patches that include readline, GNU 
scientific library, or similar GPL code without causing FSF conflicts.
It would not be a replacement for business legal advice, but may help to 
clear things for bystanders.
OTOH, the experiment would probably mean nothing as the analogous case 
is that Linux kernel is GPLed and blends nicely with proprietary components.
