Replying to [comment:2 simonmar]:
> When linking the binary, how does the linker know it also needs
`ws2_32.dll`?
It doesn't. Only the stub file is linked in. The stub file is a peculiar
to Windows way to produce an indirection/relocation. When the produced
binary is executed, the Windows dynamic loader takes care of the
`__imp__WSACleanup@0` symbol redirection/resolution.
> I wonder why GHCi doesn't also find `libws2_32.a`? Maybe it isn't on
the search path for some reason.
It doesn't search for `libxxx.a`, and the path searched does not include
the location of the stub file. Also, I believe the PEI386 handling in
rts/Linker.c currently would be unable to load such stub files.
Please, pardon my brevity, still looking into this.
