AddImplicitInclude()

static void AddImplicitInclude ( MacroBuilder &  Builder, StringRef  File  )

static

AddImplicitInclude - Add an implicit #include of the specified file to the predefines buffer.

As these includes are generated by -include arguments the header search logic is going to search relatively to the current working directory.
