I thought that last time I failed to build it, Gentoo was to blame so I
tried again today on an amd64 FC4 host, and that worked for i386.
Again, I had to delete the empty files to get that far.

I also had to remove 3-level page tables option, otherwise I get this:
  HOSTCC  scripts/bin2c
  CC      init/main.o
In file included from include/asm/pgtable.h:30,
                 from include/linux/bootmem.h:7,
                 from init/main.c:30:
include/asm/pgtable-3level.h: In function ‘pud_clear’:
include/asm/pgtable-3level.h:74: warning: implicit declaration of
function ‘set_64bit’
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
(...) Lots more warnings about set_64bit... Then the build fails.


Any fix for the GCC errors on arch/um/include/sysdep/stub.h would be
much appreciated (I have to compile on these hosts to be able to use the
pcap network driver):
  CC      arch/um/kernel/skas/clone.o
arch/um/kernel/skas/clone.c: In function `stub_clone_handler':
arch/um/include/sysdep/stub.h:41: error: can't find a register in class
`BREG' while reloading `asm'
arch/um/include/sysdep/stub.h:62: error: can't find a register in class
`BREG' while reloading `asm'
arch/um/include/sysdep/stub.h:51: error: can't find a register in class
`BREG' while reloading `asm'
arch/um/include/sysdep/stub.h:84: error: can't find a register in class
`BREG' while reloading `asm'
make[2]: *** [arch/um/kernel/skas/clone.o] Error 1
make[1]: *** [arch/um/kernel/skas] Error 2
make: *** [arch/um/kernel] Error 2

Or shall I bug the GCC guys?

Thanks
Antoine
