Just tried to compile winsamp.d (dmd package 
folder--dmd/samples/d),exactly the same issue.Many many years ago 
I once played with this winsamp.d for testing win32 api 
(configuration ok or not) and it get passed without those two 
pragma.I am thinking whether it is related to MS VC lib path or 
MS VS path.
