Tadaa!  Here is the more detailed info.  If you try to do

$ make install-headers no_deps=t

in the configured Hurd sources, you get:

make[1]: Entering directory `/gnu/build/hurd-obj/libtrivfs'
i386-gnu-gcc -O -E -x c  -I. -I../../hurd/libtrivfs -I.. -I../../hurd

directory
make[1]: *** [fs.sdefsi] Error 1
make[1]: Leaving directory `/gnu/build/hurd-obj/libtrivfs'
make: *** [libtrivfs-install-headers] Error 2

When I copy the file bits/utsname.h into /include/bits/utsname.h, the
command succeeds.

Now, when trying to compile glibc:

i386-gnu-gcc mach_error.c -c -O2 -Wall -Winline -Wstrict-prototypes 
-Wwrite-strings -g -Wno-parentheses      -I../include -I.

When I copy the file bits/stdio_lim.h into /include/bits/stdio_lim.h, it
goes on.

Note that there is still the problem that the RPC stubs in mach/ are not
generated (see libc-alpha), and I am very confused by the makefiles.
It seems that this problem occurs only with gcc 3.1, which is obscure.

Thanks,
Marcus
