Searching for which libraries are linked can then become frustrating and confusing since they may be included in an obscure place, and for all relevant compilers there is no difference between specifying them from make and in a source file. The easiest solution is to just always link them from make and remove any source level linkage.

I think this came about with one of the early Microsoft contributions to have transferTo optionally use TransmitFile on Windows. This create the dependency on Mswsock.
