#13 Compile fails under solaris8/sparc

[Saverio Pangoli]

Platform:

SunOS epsilon 5.8 Generic sun4u sparc SUNW,Ultra-5_10

Description:
IPPROTO_IPIP is not redefined as IPPROTO_ENCAP, causing compilation to fail.
It works fine with Solaris 2.6

Proposed fix:
Change conditional defines in igmp.h

Compiler output:
