fix coqide double module linking (error on OCaml 4.03)
Linking the same module twice in OCaml can have problematic unintended
consequences and lead to hard-to-understand bugs, see
http://caml.inria.fr/mantis/view.php?id=4231
http://caml.inria.fr/mantis/view.php?id=5461
OCaml has long warned when double-linking happens
Warning 31: files FOO and BAR both define a module named Baz
In 4.03 this error was turned into a warning by default.
Coqide does double-linking by passing both
xml_{lexer,parser,printer}.cmo and lib/clib.cma that already contains
these compilation units to bin/coqide.byte. To fix compilation of
Coqide under 4.03, the present patch removes the .cmo from the
command-line arguments.
P.S.: I checked that this patch applies cleanly to the current trunk
(b161ad97fdc01ac8816341a089365657cebc6d2b). It should also be possible
to add it as a patch on top of the 8.5 archives (for example those
distributed through OPAM) to make them compile under 4.03.
