Need C programmer to verify gcc-4.0 FTBFS patch

[Christian Hammers <ch@debian.org>]

Hello

(please Cc me)

The latest upstream version of libnet-rawip-perl won't compile with gcc-4.0
and produces lot of the below quoted errors. I produced a patch but would like
a real C programmer to verify what I tried.

I tried to understand the changelog of gcc-4.0 and think I learned that the
left hand side has to be a "plain simple variable without any frills" and as
a typecast never changes the actual value the removing it should be fine, or?

thanks,

"pktr" and "user" are "struct"s and "ihl" an "u_int".
