The message is to be understood literally: in order to compile
assembly code to machine code, ocamlopt relies on an external
assembler. I suppose you use either the mingw or cygwin version, so
the name of the assembler is "as". You must make sure you installed it
with cygwin.
With a .mli, there is no object created, so no external command is
required. Similarly ocamlc generates bytecode all by itself, so there
is no such problem (as long as you don't use the -custom option.)
