compilation fix for PCH-less compilation after the last change

12 // FIXME FIXME FIXME:
13 // extract different backends in different files (better yet, make backends
14 // dynamically loadable...), they have nothing to do with each other and this
15 // file is huge and also separate the standard contents from our code itself

95 // idl using the midl compiler that comes with visual studio
96 // ($Microsoft Visual Studio$/VC98/bin/midl.exe on VC6) with the /h argument

104 // Player 6.4 SDK.
