I don't use cygwin, but, perhaps, the answers on the eCos site.



Users who have downloaded eCos previously and now wish to download
additional toolchains should re-invoke the eCos installer, specifying
the -t switch on the installer command line as follows:

      sh ecos-install.tcl -t

NOTE: Recent eCos toolchains based on GCC 4.x may fail silently if the
Cygwin package libmpfr1 is not installed.
