Shouldn distcc check gcc versions?
It might be a good idea for distcc to check the version of gcc on all the volunteer machines. However this turns out to be hard to do completely reliably, because some programs which both call themselves “gcc 3.2.1” behave differently, presumably because of vendor patches or because vendors have shipped pre-release code. So since automatic detection would not be a reliable solution, for the moment we depend on the user to make sure they have compatible versions installed.
