No, there is none. Output looks like:
.seh_proc _ZN2N43._91CIiE3fn2ES2_
_ZN2N43._91CIiE3fn2ES2_:
.LFB11:
.seh_endprologue

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.
