Note [mingw-w64 name decoration scheme]
What's going on with name decoration? Well, original code
have some crufty and ad-hocish paths related mostly to very old
mingw gcc/binutils/runtime combinations. Now mingw-w64 offers pretty
uniform and MS-compatible decoration scheme across its tools and runtime.
The scheme is pretty straightforward: on 32 bit objects symbols are exported
with underscore prepended (and @ + stack size suffix appended for stdcall
functions), on 64 bits no underscore is prepended and no suffix is appended
because we have no stdcall convention on 64 bits.
See #9218
