If you are manually adding the *.lib files to your link dependencies,
then you are also responsible for linking against any DLLs they depend
on. If you use GYP to build your project, it will do that
automatically for you.
Grep tools/gyp/v8.gyp for the relevant 'link_settings'; I believe it
currently consists of just -lwinmm.lib -lws2_32.lib.
