[fpc-pascal] Trying to convert some C code

since this is from a c library you should define {$packrecords c} on
the unit with this code.

  BIGNUM = bignum_st;

  PBIGNUM = ^bignum_st;

  bignum_st = record
    d: PBN_ULONG;
    top: cint;
    dmax: cint;
    neg: cint;
    flags: cint;

  TBN_bn2hex = function (const a: PBIGNUM): PChar; cdecl;

  As you can see this code won't compile, you need to also find the
declaration of BN_ULONG and define it. Also put ctypes on the uses
