Codegen problem "ordinal type expected"
I am wrapping OpenSSL's libcrypto and am having particular trouble with its MD5 library. When cImport-ing the MD5 header file, the following error is thrown:

`macros.nim(601, 18) Error: ordinal type expected`

By trial and error with cSkipSymbol I was able to figure out that the problem was with the following piece of code generated by Nimterop:

```
type
  MD5state_st* {.bycopy.} = object
    A*: cuint
    B*: cuint
    C*: cuint
    D*: cuint
    Nl*: cuint
    Nh*: cuint
    data*: array[(64/4), cuint]
    num*: cuint
```

I suspect that the line `data*: array[(64/4), cuint]` is the source of the problem. Maybe uint's cant be used in that context?
