[Scilab-users] compilation with OCaml 4.06

[Florian Blachère]

Hello,

Thanks for this patch, but it seems not enough to build as there is 
still some errors with Bytes/Strings:

File "src/modelica_compiler/optimization.ml", line 168, characters 49-50:
Error: This expression has type bytes but an expression was expected of type
          string
