Trivial compilation CONFIG_INET=n case

The rose_rebuild_header() consists only of some variables in case INET=n, and gcc will warn us about it.

Fits both net-2.6 and net-2.6.25.

Applied to net-2.6, thanks.

Hi,

Rose network is using extensively AX25 IP encapsulation for routing AX25 packet radio frames via Internet nodes such FPAC nodes.

ax25ipd (from ax25-apps) is doing frame encapsulation and decapsulation.

Since version 1.0.3 patch by vk5asf ax25ipd is checking every 5 minutes hostnames for dynamic DNS.

There was still a failure possibility when the program is started in case of unsuccessful resolving remote host ip from its hostname was unsuccessful.

I introduced a simple error warning instead of an exit as the remote host could be temporary down and the address will be checked again periodically later.

The patch against ax25-apps-0.0.6.2 (kernel 2.6 compatible) can be found here :

http://f6bvp.free.fr/logiciels/ax25/ax25-apps-0.0.6.2.diff

and ax25-apps-0.0.6.2 is here :

Hi,

I found that my previous patch for ax25ipd did not give good results. Here is the new patch.
