Reverts commit: a4202146b8d26b6615bbab986383fe0afae60d77

Testing inet_pton with the help of Steffen. Acording to Steffen we can use
!(NTDDI_VERSION >= NTDDI_VISTA) to identify that the specific Windows version
has this function defined or not, if so we can use the Windows version.
Reverting this commit to avoid to overwrite the Windows' function. And
see the original error that happened before this commit.
iis: Checks Win version before declare inet_pton

Checking for `!(NTDDI_VERSION >= NTDDI_VISTA)` to decide whenever or not
to declare the inet_pton function.
