These should all still work fine with anoncvs.

The toplevel configure script looks for host-side sources in two
places. First it looks for a toplevel host subdirectory. Then it
searches for package-specific host-side support, i.e. host
subdirectories within each package.
The toplevel host subdirectory is a separate CVS module so it will not
automatically be present in an anoncvs tree. If you really need it
then you will have to do a cvs checkout of the ecos-host module. Most
people just use the existing binaries.
A number of packages have their own host-side support, e.g. for the
Linux synthetic target. I believe that, at present, if you are
configuring on a cygwin host then there is nothing to build for any of
these packages. Hence the make is a no-op.
