What happens if you then try to link a trivial eCos application which declares a static string object? I suspect that is going to pull in __cxa_guard_release() again, which will take its __cxa_pure_virtual() from libsup++.a instead of libtarget.a. So deleting the static from the declaration is only moving the problem, not solving it.
