It appears that there is something missing in your Cygwin installation
which is causing arm-eabi-gcc to fail silently. My own Cygwin
installation includes packages from the "Base" and "Devel" categories
plus a few others which are unlikely to be relevant. If you are in a
hurry, try installing all the Cygwin packages from the "Devel" category
using the Cygwin Net Release Setup Program. If you have more time, it
would be helpful to determine precisely which of these packages are
required.
