cgo: Duplicate definitions when linking

[Albert Strasheim]

Hello all

I am playing with the new cgo.

Consider the case where you have two packages, pkg1 and pkg2, that
both call the same C function in the same library.

If a binary imports both packages, you get an error at link time:

pkg2.a(pkg2.cgo2.o): duplicate definition of _cgo_Cfunc_somefunc

Maybe this falls under the "don't do that" category, but I can think
of cases where you might want to do this, e.g., wrapping a big C
library as multiple packages and calling some general C code from all
the subpackages.

rsc?

Regards

So the issue is that two different libraries have
chosent to wrap, say, C.strtol?

Okay, please file a bug.
