[kaffe] Kaffe for OpenWRT

[Richard Brady]

Thanks Dalibor,
compile is asking me to report some warnings:

configure: error: Failed to get size of sa_family in struct sockaddr.

Then it errors as you can see.
Are the warnings and this fail related? Does it look like a problem with my
environment or the mipsel compile itself?

Thanks

Rich.
