Hi Ariel,

Those fixes are important, but as Tom said, only for 4.0.2 if we do one.

However, they'll need to be looked at with care, as they fix some odd
bugs in the compiler and I'm not sure how stable they really are.

They may behave well in trunk because of other patches that were
noticed and fixed, but back-porting just those patches may introduce
instabilities that weren't fixed in 4.0.

Given that we release a new version every 6 months, and that we
(Still) don't have (community) support for older versions, you may be
better off using 5.0 instead.

Thanks for creating the merge requests, though. Let's look at them
when/if 4.0.2 comes along.

cheers,
