True, but it's worse than that: GNU ld also supports something like
# Names inside the 'extern' block are demangled names.
extern "C++"
{
std::_6::*;
std::*
};
(this is an example from the libstdc++ version scripts). Since the name
mangling is compiler dependent, this may get intricate to support properly.
There may be even more GNU extensions. Hopefully the GNU ld manual
describes all of them.
