The normal case of using the linker is for C and C++ programs.  When
linking such programs, the linker should report symbols using names
that are meaningful for C and C++.

I would have no objection in principle to making this depend upon a
command line option.  Unfortunately, compilers traditionally do not
pass any such command line option.  gcc must work with either a native
Unix linker or the GNU linker.  It can not pass a command line option
that will only be understood by the GNU linker.  Therefore, I don't
see any way to make this work correctly based on a command line
option.

My conclusion is the reverse of yours: we should provide a command
line option which turns off the symbol name demangling.
