Neither.

It's kinda weird actually. First you have to run winebuild on the object
files, so it can generate import stubs. Then you have to assemble (yes,
assemble) and link these stubs to your object files. This is because of
the way importing functions from Wine DLLs works (it's designed to be
compatible with Windows).

Luckily, you don't have to do all this by hand. The winegcc tool does
all this for you. So, you invoke wineg++ instead of plain g++. Also, you
have to tell it you want to link to kernel32.dll by passing it -lkernel32.

Hope that helps.
