Searching for libmpc yielded > libmpc3 - am I to assume that this is an appropriate substitution? It looks like the Cygwin gcc4 and libmpc1 packages have been withdrawn. I suggest you try the gcc-core and libmpc3 packages instead. You may need to create /bin/cygmpc-1.dll as a symbolic link to /bin/cygmpc-3.dll in order to satisfy the dependencies of the eCos toolchains. Does this work for you?
