Change BSTR() from a macro producing a compound literal to an inline function returning the same value. This works for all existing uses, and avoids a warning from BSTR(NULL) (the macro expansion contained strlen(NULL); this was valid code because the strlen call was never evaluated, but still triggered a GCC warning).
