Hello everyone,

I am currently taking a look at the results and especially warnings
from the curl autobuillds.

For example this one here contains quite a lot of dereferencing
pointer warnings:

I have searched around and found this related stackoverflow question:
http://stackoverflow.com/questions/3464888/

It seems like this is a gcc problem that cannot be fixed easily.
Anyway, I just wanted to inform you about these warnings and ask if
anyone knows a solution for them.

Best regards,
Marc
