USE_PORTABLE_COROUTINE_HANDLE has no effect

[huang-jl]

In the ReadMe (at main branch) it said "It can be activated with macro USE_PORTABLE_COROUTINE_HANDLE".

However, I cannot find any usage of "USE_PORTABLE_COROUTINE_HANDLE" in this repo.

After reading the code at coroutine/frame.h, I think there is no way to use the coroutine_handle in the STL in linux with g++. That means I can only use your implementation in coroutine/frame.h

Thanks for reporting @huang-jl . Maybe https://github.com/luncliff/coroutine/tree/1.5.0 work for you.
Sorry. I couldn't maintain this work for a long time because of real life stuffs.
(I do want to update something, but currently focusing on work...)

@luncliff Fine, thanks for your quick reply.
