Well, according to their home page, this probably isn't a Cygwin
toolchain - http://www.yagarto.de/ says:

  Why another GNU ARM toolchain?
  Initially I was searching for a toolchain with the following features:
    * not based on Cygwin
    * works with Eclipse
    * cheap for the beginners

... so I'm going to go out on a limb and presume that this isn't a
Cygwin based toolchain (since they seemed to want to avoid that for some
reason, and since other pages on their site mention this is a MinGW
based toolchain.)

If this is the case, then unfortunately, you will have trouble with
symbolic links, paths, and probably other areas, as well.

Unfortunately, this means that using this toolchain with Cygwin is
probably *not* what you want to do.  I'm glad my advice on managed
mounts, etc. helped you get a *little* further, but I suspect your best
bet is to uninstall Cygwin, and follow the installation instructions
that they provide for their development environment:

  http://www.yagarto.de/howto/yagarto1/index.html

It also means that your questions about the toolchain should be directed
at Yagarto's own support forum, instead of this mailing list:

Good luck!  I hope things work out for you.
