For template libraries, LGPL and GPL are almost equivalent because
it's impossible to fulfill the relinking requirement without
distributing full source code.  Therefore, the FSF adds special
exceptions to GPL-covered code instead.  See the C++ run-time library
and the GNAT run-time library for examples (Ada is quite similar to
C++, at least in GCC's implementation).
