DMD's kernel32.lib missing symbols?

[simendsjo]

Not sure how I can search for symbols in the library, but it seems the 
library is missing functions.
I've tried using coffimplib on kernel32.lib from the Windows SDK, but it 
neither produces a new library or give me an error.

What Windows version is the library based on?
How can I check what symbols exists?
Is there a way to convert WinSDK's library to omf?
