Can't you manipulate the -I lines for gcc? I.e. when we are compiling
Linux specific code put the Linux header directory before the Hurd
one, and vice versa.

Perhaps, the building process of the Hurd still confuses me. I think
this requires a lot of work and I'm almost sure there is an easy way.

In recent libc's on GNU/Linux rtentry is in <net/route.h>.  Maybe that
another way of fixing the problem...

No, I'm using that one. The problem is that the linux header files conflict.

Thanks,

Marco,

From just poking around google for a while it appears that ortentry is old 4.3 compatibility so it would appear to me that /bits/ioctls.h should probably use rtentry. Or you would have to check in your code in order to have to support 4.3 and use ortentry in that case otherwise, use rtentry..

Does that help any or am I just blowing more hot air about things I know nothing about?? :-)
