Hi Jonh,

Are such implementations (in pure.cxx) useful? I'm looking on linker
group

    GROUP(libtarget.a libgcc.a libsupc++.a)

    $ nm install/lib/libtarget.a | grep __cxa_pure_virtual
    00000000 T __cxa_pure_virtual

Okay it came there from infra_pure.o. Is it right? But, there is next
implementation in libsupc++.a.

    $ nm i386-elf/i386-elf/lib/libsupc++.a 2>/dev/null | grep __cxa_pure_virtual
             U __cxa_pure_virtual
    00000000 T __cxa_pure_virtual

I think arm-eabi chain is the same.

RFC: What kind of implementation will be used then? Well, using 'ar x' I
would answer :-) but may be you just know.

Thanks for any clarifications,

Sergei
