Can you verify with a simpler testcase like

int foo (int *u)
{
  return *u;
}

?  On x86_64-linux with -m32 I see for your code

_Z25_pei386_runtime_relocatorP11per_process:
.LFB221:
        .cfi_startproc
        pushl   %ebp
        .cfi_def_cfa_offset 8
        pushl   %edi
        .cfi_def_cfa_offset 12
        pushl   %esi
        .cfi_def_cfa_offset 16
        pushl   %ebx
        .cfi_def_cfa_offset 20
        subl    $92, %esp
        .cfi_def_cfa_offset 112
        .cfi_offset 5, -8
        .cfi_offset 7, -12
        .cfi_offset 6, -16
        .cfi_offset 3, -20
        movl    112(%esp), %eax
        imull   $1000, 128(%eax), %edx

which looks ok.  So it must be a *-cygwin specific issue.
