GPL forbids any clauses about non-commercial, non-military, 
education-only, and any other clauses restricting the freedom to use.
(section 7 out of 17)

   http://www.gnu.org/copyleft/gpl.html

But some other documents may be easier to interpret (but the following are 
about what is a free license, they aren't about GPL-compatibility per se).

FSF's Free Software Definition lists four essential freedoms, the first 
one being: «The freedom to run the program, for any purpose».

   http://www.gnu.org/philosophy/free-sw.html

OSI's Open Source Definition's sixth item (out of ten) states: «the 
license must not restrict anyone from making use of the program in a 
specific field of endeavor.»

   http://www.opensource.org/docs/definition.php

I think that it's clear enough.

What's more difficult to grasp is how all the different licenses interact 
with each other when you use or don't use plugins together...
