Currently we use gnumach as it is in the Hurd cvs repository at
subversions.gnu.org. The variants Okuji mentions are in development, most
likely oskit-mach done by Roland McGrath will take over at some point. The
char device glue layer was written by Okuji and extended a little by me, but
it is probably a dead end (can be found on alpha.gun.org in the contrib area
of gnu/hurd).
Responsible are the Hurd authors, mainly Thomas and Roland.

Can you speak about the nature of the modifications?

Well, Thomas Bushnell, BSG ([EMAIL PROTECTED]) is the one to talk to about
Mach issues related to the Hurd.

Well, there is a hurd info manual, but it mostly covers the Hurd libraries.
You will find the interfaces in hurd/*.defs, and little else in the Hurd
makes direct use of Mach features (grep is your friend :)
