Unfortunately, this will not be sufficient. The problem is that the
libsupc++.a shipping with Ubuntu's GCC-4.1 compiler has the stack-protector
feature enabled and hence is not affected by compiler flags for the L4
packages. The attached patch is a work around for this problem. Another
option would be to compile your L4 tree with GCC 3.4.6.
