description:
Add a "gcc is stupid" comment to the previous change, as even
the most cursory analysis shows that the var ("eg") is not (cannot
be) used unitialialised, just gcc is too dumb to work it out.

In this case, the code could be rewritten easily enough to
appease even gcc, but that would cause unnecessary code churn,
and some minor duplication, so just put up with the nonsense init...
