compiling 1.4 for freebsd 5.3 errors

[Daniel J Drake]

I'm compiling kerberos 1.4 for freebsd 5.3 and get the following build 
errors:

*** Error code 1

Here is the function

krb5_error_code
krb5int_translate_gai_error (int num)
{
    switch (num) {
#ifdef EAI_ADDRFAMILY
    case EAI_ADDRFAMILY:
        return EAFNOSUPPORT;
#endif
    case EAI_AGAIN:
        return EAGAIN;
    case EAI_BADFLAGS:
        return EINVAL;
    case EAI_FAIL:
        return KRB5_EAI_FAIL;
    case EAI_FAMILY:
        return EAFNOSUPPORT;
    case EAI_MEMORY:
        return ENOMEM;
#if EAI_NODATA != EAI_NONAME
    case EAI_NODATA:
        return KRB5_EAI_NODATA;
#endif
    case EAI_NONAME:
        return KRB5_EAI_NONAME;
    case EAI_SERVICE:
        return KRB5_EAI_SERVICE;
    case EAI_SOCKTYPE:
        return EINVAL;
#ifdef EAI_SYSTEM
    case EAI_SYSTEM:
        return errno;
#endif
    }
    abort ();
    return -1;
}

I put in code to check if EAI_NODATA was defined and it wasn't.

I see that EAI_NODATA is #undef'd and then #defined in fake-addrinfo.h:
#undef  EAI_NODATA
#define EAI_NODATA    7

This code in only included in the build if HAVE_GETADDRINFO is not 
defined.  Looking at autoconf.h, I see:
#define HAVE_GETADDRINFO 1

This stops EAI_NODATA from being #defined.

I don't want to go against what configure detects because its generally 
correct, but the output of configure doesn't result in a sucessful build. 

If anyone has any hints, I would appreciate it.
