This is what I'm executing:

ocamlopt -output-obj -o ocamllibrary.o library.ml
cl /c my_plugin.c /I"C:\\wodi32\\opt\\wodi32\\lib\\ocaml\\std-lib"
cl /c ocaml_stub.c /I"C:\\wodi32\\opt\\wodi32\\lib\\ocaml\\std-lib"
flexlink -chain msvc -exe -o my_plugin.exe my_plugin.obj ocaml_stub.obj
ocamllibrary.o plug.lib -lasmrun -lgcc -L
"C:\wodi32\lib\gcc\i686-w64-mingw32\4.8.2"
