Compare the formatting of your for() statement above with the others in the file - you should use the existing style in your patch.
I was never a fan of that style, but ok.
In general, writing patches is like repairing holes in a plaster wall - the aim is to blend your patch in with what is already there so it's impossible to work out where the patch begins/ends without reading the SVN log.
Also as per my comment on your last version of the patch, you need to use target_long() as per the existing code in lstore.
Do you mean write_long()? This is what lstore uses. Why use this function as oppose to the code I have now?
Oh sorry - yes, you are correct, it is write_long(). Mainly for two reasons: 1) to preserve style and 2) ensure that cross-compilation works correctly.
Ok, I finally figured out how to include cross.h. Does this code look good?
