I will write necessary wrappers for struct statfs and related syscalls.
They will be ABI compatible with glibc 2.3.0 on kfreebsd-i386,
symbol versions will be unchanged.

But I would like to drop some ugliness from (now user space only) headers, 
like

 char f_mntfromname[sizeof(long) == 8 ? 72 : 80];

It will mean break ABI for alpha, the only other arch with sysdeps bits now.
It can be fixed, when alpha bits will be ported for 2.3.5 via symbol versions
change. In fact, I think we don't have to care about alpha ABI much.

On the other hand, what about kfreebsd-amd64 ?
(yes, I brought it up again).

Things, that have to be solved:

* archive 
        ? ftp.debian.org 
        ? ftp.gnuab.org 

* gcc (toolchain) support
        cross
        biarch on i386
        native on amd6
        biarch on amd64

* glibc
        2.3.6 based

* kernel
        ? 5.4 or 6.0

* buildd machine
* buildd admin

* porting machine
* porting machine admin


I volunteer for glibc bits ;-)
