Yes just now, and it's not good.

It is possible to beat eclipse mostly into submission by starting with a
very limited $PATH (env .../4.6.2/bin:/bin:/usr/bin eclipse). Those
avr-gcc preferences are then changed to (in my case)
/opt/cross/avr/lib64/gcc/avr/4.6.2/bin, still with path source "system".
Ok so far.

Starting eclipse normally again with the usual $PATH does not however
change that setting back, otherwise the feature would be of no use. That
4.6.2/bin is not in the normal $PATH.

And eclipse is being smart-arse here too, one can't set a path here of
/nowhere, or something that's already in, like /bin.

Ok, that explains what I've been seeing.

Yes, but I have a script for that, run-avr-gcc-462 which prepends the
versioned bin directory to $PATH before doing an exec. That script is
needed for running the Arduino IDE, with which neither the compiler name
nor the PATH can be adjusted. Adjusting the compiler name would be a
nightmare anyway (too many executables), and I sure don't want to
remember or type "/opt/cross/avr/lib64/gcc/avr/4.6.2/bin" all the time.

Sorry, from my point of view I give this feature a pain-for-no-gain
rating... :-(

Perhaps it's possible to set up a toolchain for each gcc version here.

Thanks, will do.
