...specifically, the /AL option? I am porting some ancient C (a Freescale nee Motorala M68000 simulator) and I can't find it on MSDN. Google retrieves many non-related links, and the Wayback Internet Archive chokes beyond the "Product Release" page. Note that this switch seems not to be present in version 6, but resurfaces in .Net as: "/AL Specifies a directory to search to resolve file references passed to the #using directive" These files are neither C++ nor C#, su that ain't right...
an example: cl -c -AL CODE1.C
