Hi all, again.

I've installed proper toolchain (arm-linux, from CodeSourcery). Along
with this, I also (re)moved /usr/include/asm, and created following
sym links:
/usr/include/asm -> kernel_dir/include/asm-arm
/usr/include/linux -> kernel_dir/include/linux

As soon as I start kernel build (make ARCH=arm CROSS_COMPILE=...) I got:

  CHK     include/linux/version.h
make[1]: `include/asm-arm/mach-types.h' is up to date.
  CHK     include/linux/utsrelease.h

Without /usr/include/asm and /usr/include/linux symlinks I get errors
that some .h files are non-existant.

From my perspective it looks like a cygwin "problem". Sorry if I'm not righ.

Probably sys/types.h in cygwin and Linux are not the same, something
that is defined in linux/types.h in linux is also defined in
cygwin/types.h, etc. I can probably copy /usr/include from my Linux on
the Cygwin host, and probably I will be able to cross-compile kernel,
except the things that should be compiled for the host (cygwin in my
case).

Any comments?

Greetings
