I assume the delay means you have built it, and your results matched
mine, in which case, \o/

I can hardly believe it no longer only exists on my machine :) Did you
manage to run it?

Thank you for changing pthread_t to be pointer-sized, I was going to
do that next.

Here's some of my own news: I've got enough of Hurd ported and built
to get this:

$ file ext2fs/ext2fs ext2fs/ext2fs.static exec/exec proc/proc
ext2fs/ext2fs:        ELF 64-bit LSB executable, x86-64, version 1
(SYSV), dynamically linked, interpreter /lib/ld-x86-64.so.1, for
GNU/Hurd 0.0.0, with debug_info, not stripped
ext2fs/ext2fs.static: ELF 64-bit LSB executable, x86-64, version 1
(GNU/Linux), statically linked, for GNU/Hurd 0.0.0, with debug_info,
not stripped
exec/exec:            ELF 64-bit LSB executable, x86-64, version 1
(SYSV), dynamically linked, interpreter /lib/ld-x86-64.so.1, for
GNU/Hurd 0.0.0, with debug_info, not stripped
proc/proc:            ELF 64-bit LSB executable, x86-64, version 1
(SYSV), dynamically linked, interpreter /lib/ld-x86-64.so.1, for
GNU/Hurd 0.0.0, with debug_info, not stripped

Trying to run it, it of course does not work:
ext2fs: part:1:device:hd0: Invalid argument

This is because:
- I'm building --without-parted
- gnumach gets built without the Linux disk drivers
- I'm not even attaching a hard drive to the VM...

How do we proceed? I don't know enough about rump to get it building;
so enabling the in-kernel Linux drivers seems preferable. Any tips on
how I would do that? Are the Linux drivers ancient enough to require
their own porting to x86_64, or will they just work?
