libsc functions don't work on Windows

[efaulhaber]

This one-liner

sc_package_id()

yields

julia> sc_package_id()
CBinding.Cglobal{Int32}(Ptr{Int32} @0x00007efe185a691c)

on Linux but

julia> sc_package_id()
ERROR: could not load symbol "sc_package_id":

on Windows.
This happens with multiple (maybe all) sc_ functions.

Lucky me, I can reproduce the observed behavior on Windows \o/. I do not know yet, however, how to even approach this bug...
