> Could you explain what is special about the `WSACleanup` symbol here?
Why is it different from any other symbol that we import from a DLL?
`WSACleanup` just happens to come prior to other such symbols in the
symbol table of the PLOF:
{{{
$ objdump -x network-2.3.0.14/ghc-7.4.2/HSnetwork-2.3.0.14.o |grep __imp__
[733](sec 0)(fl 0x00)(ty 0)(scl 2) (nx 0) 0x00000000
__imp__WSACleanup@0
[1548](sec 0)(fl 0x00)(ty 0)(scl 2) (nx 0) 0x00000000
__imp__accept@12
[1787](sec 0)(fl 0x00)(ty 0)(scl 2) (nx 0) 0x00000000
__imp__inet_ntoa@4
[2047](sec 0)(fl 0x00)(ty 0)(scl 2) (nx 0) 0x00000000
__imp__GetLastError@0
[2632](sec 0)(fl 0x00)(ty 0)(scl 2) (nx 0) 0x00000000
__imp__WSAStartup@8
}}}
> After all, we call a lot of functions that live in DLLs.
We only manage to do that for the fully linked by GNU ld executable
images, which get loaded into the memory by the Windows dynamic loader,
which, in turn, specially processes these 'import' symbols.
