I've not built anything on windows, let alone set up a build environment 
there, but "just copy random files around because they are asked for" sounds 
like a bad idea in nearly all cases.  Your errors seemt o indicate that at 
least some other header files are missing as well.

Next thing (it probably isn't the reason for your trouble here) are your 
compile flags.  If you ever run into runtime trouble, probably nobody will 
help you with flags like -O3.

Just my 2¢,
Daniel
