Okay, problem solved. I forgot to add CYGPATH to Windows environment 
variables. Kudos to Codesourcery guys for the hint.

By the way - it's not quite plug and play. When debugging for the first 
time, Eclipse complains:

[quote begins]
Can't find a source file at "c:\ecos-c\projects\...[snip]...\vectors.S"
Locate the file or edit the source lookup path to include its location.
[quote ends]

The "\ecos-c" should have vanished when cygpath converted path to 
windows format. In my case is still there and breaks the path.

Pressing the button "Locate File" and browsing to the source 
automatically adds a path mapping from "c:\ecos-c" to "c:\" which heals 
the defective path. I can proceed with actual debugging.
