building linux target runtime on win2000 cygwin host

[Maxa Petr <Petr dot Maxa at siemens dot com>]

Hello ,

I have simple question, whether it is possible to build Linux runtime files
from Win2000 Cygnus host or not. I would welcome if someone can share its
experiences. If the building of these files is not possible from Win2000,
are they available some on web for download? 

I have read the http://www.objsw.com/CrossGCC/ and
http://www.nanotech.wisc.edu/~khan/software/gnu-win32/cygwin-to-newlib-cross
-howto.txt, but I am still not sure on the mater. I have also tried building
a CrossCompiler with --target=i686-pc-linux-gnu on Win2000 and Cygwin.

I used the following sources for the build:
  binutils-2.13.2.1.tar
  gcc-3.2-3-src.tar (small patch for __mempcpy applied)
  newlib-1.11.0.tar.gz

The build was partly successful - with a possibility to compile sources, but
not being able to link them as e.g. crt1.o is missing.

During building of GCC I got the following error:

mkdir libgcc
if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi

I also wanted to use a "One Pass Installation", but the script
one-tree-1.6.sh refused my sources. After that I have looked at "configure"
files in each package and found, that they are different. After this I've
abandoned the "One Pass Installation" at all.
  
Thanks for Your answer.

Petr Maxa.
