[Lazarus] Is there some way packages can be designed to make developing them for different versions of Lazarus easier?

[Frank Church]

In relation to the earlier thread
http://lists.lazarus.freepascal.org/pipermail/lazarus/2011-July/064884.html,
are there some guidelines package designers must apply to ensure that they
can be compiled by different versions and builds of Lazarus at the same
time?

I think it is a good idea as upgrading to new versions tend to break code
over trivial changes that can be fixed with a few ifdefs.

PS. Are Lazarus .lpi files downward compatible? As they as XML based I think
it is a matter of older versions neglecting fields and attributes they don't
recognize.
