0005566: Duplicate Dynlink.is_native as Sys.is_native

Notes
(0007223) protz (manager) 2012-03-29 10:38	I can already run the following sequence in a toplevel: #use "topfind";; #require "dynlink";; Dynlink.is_native;; Is that not enough? There's different Dynlink implementations in the source tree, so it's easy to define is_native as being true or false, but I'm not sure how we would do that inside the Sys module...

(0007233) Hendrik Tews (reporter) 2012-03-29 11:46	Having Sys.is_native is useful especially in those cases where the dynlink library is not required. In those cases one doesn't really want to load findlib and dynlink to access just one boolean. One can always check at program invocation whether one is going to run a native program and use different source code or additional arguments for the native program.
