Three problems:
1) -c turns linking off, while you really want to do a
  (partial) link here.
2) The compilation of lexer.ml already
   produces lexer.obj, so you give lexer.obj both as input and as output
   to the partial linker, which can break things.
3) With the MSVC port, the output of the partial linker is a .lib file,
   not a .obj file, so it would be prudent to name the output 
appropriately.

Try this instead:

ocamlopt -output-obj -o lexer.lib lexer.ml

Hope this helps,
