[ECOS]library build errors following ecos- and toolchain update - at91sam7x-based target

["Bob Brusa" <bob dot brusa at gmail dot com>]

Hi
Having done some work with ecos-3.0 and a GNUARM-toolchain, it thought its  
time to update my system. But I run into troubles. What I did:
a) installing a clean ecos-3.0 from a mirror in Germany - not for ecos,  
but for the tools that come with it (configtool.exe)
b) created an empty directory c:\cygwin\ecoscvs and run the checkout  
command of cvs (as described in http://ecos.sourceware.org/anoncvs.html.
c) run the cvs-update command. ecos is at c:\cygwin\ecoscvs\ecos
d) downloaded and installed the most recent toolchain from codesourcery:  
arm-2009q3-68-arm-none-eabi.exe
e) added my target to ecos (the one of b+c) using the administrator  
command of configtool.exe
f) saved the configuration and created the directory tree and then started  
build of my library (at c:\ecos\icb4)

My system is Windows XP prof. and cygwin, including dev. tools is  
installed.
The environment variable CYGPATH is set to c:/cygwin/bin/cygpath and
the repository in configtool is C:\cygwin\ecoscvs\ecos

The build does not go very far, but soon stops with an error. Here is what  
I get:

...cut

It seems that the compiler has a problem with c:\cygwin - which it should  
use as a prefix to the path. Any ideas how to fix this?
Thanks for help and regards Robert
