>Description:
Title pretty much says it all...  There's an uninitialized variable on line 995 
of /sys/netinet6/ip6_output.c and it breaks a kernel build.  

A quick change to:
struct ip6_frag *ip6f = 0;
...gets things going again.
>How-To-Repeat:
Compile the Atari kernel with:
options IPSEC
options IPSEC_ESP
options IPSEC_NAT_T

...and that should be sufficient to reproduce the issue.
>Fix:
See above.
