[SPEC2DEF]

Browse source 
Add support for adding aliases when exporting data by specifying the -withalias switch. This will cause MS LINK to generate _FooVar as an alias alias for _imp__FooVar. While this looks wrong and is not the way you usually handle data imports, this is what we have in the DDK for a number of data exports like KdDebuggerNotPresent, IoFileObjectType, ..., which we currently define in an incompatible way. Remove stdcall decorations on non-x86 builds
