Bugzilla Bug 226359

after some playing with flags does compile with the minimal flag set. also with
minimal berkdb ... Not with berkdb by itself

emerge dies as follows if no flags  or just berkdb are set.

 The specific snippet of code:
 *       emake CC="$(tc-getCC)" AR="$(tc-getAR)" || die "make"


I tried reemerging linux headers as well

emerge --info

ip_tunnel.h patch

It's the 'new' include/ structure that differs from the files in /usr/include;
include/linux/ip_tunnel.h doesn't include asm/byteorder.h, which eventually
defines __constant_htons.

This patch makes the minor change necessary, but may not be all that's
eventually needed if iproute2 continues to carry around its own headers.

should be fixed in cvs now
