Snaccv1.3r2 problems

Hi all!

I wrote a simple PKCS1.asn and compile it use Snaccv1.3r2 succefully
(use ..\snacc13rn\compiler\compiler\Debug\snacc.exe)
, but it will get errors when i compile pkcs1.h and pkcs1.cpp use MSVC6........

I am using winnt4.0 with SP6,MSVC6
My steps are:
step1.New a project(VC6)
step2.Add pkcs1.h and pkcs1.cpp to project
step3.In project settings,set pkcs1.cpp  "Not using precompiled headers"
step4.In project settings,add "..\snacc13rn\c++-lib\inc"(depend on path)
         and "..\snacc13rn" into "Additional include directories"
step5.compile pkcs1.cpp,19 errors:

Error executing cl.exe.


My pkcs1.asn is

PKCS1 DEFINITIONS ::=
BEGIN

RSAPublicKey  ::=  SEQUENCE {
  modulus INTEGER,
  publicExponent INTEGER}

RSAPrivateKey ::= SEQUENCE {
  version Version,
  modulus INTEGER,
  publicExponent INTEGER,
  privateExponent INTEGER,
  prime1 INTEGER,
  prime2 INTEGER,
  exponent1 INTEGER,
  exponent2 INTEGER,
  coefficient INTEGER}

Version ::= INTEGER

pkcs1 OBJECT IDENTIFIER ::= { 1.2.840.113549.1.1 }

md2WithRSAEncryption OBJECT IDENTIFIER ::= { pkcs1 2 }

md4WithRSAEncryption OBJECT IDENTIFIER ::= { pkcs1 3 }

md5WithRSAEncryption OBJECT IDENTIFIER ::= { pkcs1 4 }

END



How should i do?? 
And how could i do ?? Thanks !
