No, there is none.  Output looks like:

        .seh_proc       _ZN2N43._91CIiE3fn2ES2_
_ZN2N43._91CIiE3fn2ES2_:
.LFB11:
        .seh_endprologue
        ret
        .seh_endproc
        .globl  _ZN2N41qE
        .data
        .align 8
_ZN2N41qE:
        .quad   _ZN2N43._91CIiE3fn2ES2_
        .globl  _ZN2N41pE
        .align 8
_ZN2N41pE:
        .quad   _ZN2N43._91CIiE3fn1ENS0_1BE
        .globl  _ZN2N31qE
        .align 8
_ZN2N31qE:
        .quad   _ZN2N31D1CIiE3fn2ES2_...

The concept of weak - as present in ELF - isn't known in COFF in
general.  There is some weak, but it works only for static library and
in a limitted way.  Therefore we can't (and don't) use it for COFF
targets.

PS: I have another similiar reasoned patch for g++.dg/abi/thunk5.C on
my pile too.
