OCaml linking error: cannot find crtbegin.o -

i installed ocaml on windows xp using ocpwin couple of minutes ago. when tried compile example program, got 2 errors:

ld: cannot find crtbegin.o: no such file or directory ld: cannot find crtend.o: no such file or directory ** fatal error: error during linking file "caml_startup", line 1: error: error during linking

i can find gcc, ar , ld in bin folder, crtbegin.o or crtend.o not nowadays in installation directory or subdirectories. how resolve problem? did miss in (post) installation step?
