I try to build GNU Hurd and I've got this error when I make gnumach.gz :

mig -n -cc cat - /dev/null      \
          -user vm/memory_object_user.user.c -header
vm/memory_object_user.user.h                    \
          -list vm/memory_object_user.user.msgids                               
        \
          < vm/lib_dep_tr_for_defs_a-memory_object_user.user.defs.o
cat: illegal option -- E
usage: cat [-benstuv] [file ...]
mig: fatal: "<no name yet>", line -1: no SubSystem declaration
make: *** [vm/memory_object_user.user.h] Error 1

I searched but find nothing. Can you help me?
