diff prototype for krb5_write_message?

[Hua Ying Ling]

I'm trying to compile LPRNG with Kerberos support for MacOS X but I'm 
getting an undefined symbols for _krb5_read_message _krb5_write_message 
_krb5_xfree _valid_cksumtype.  I have included the Kerberos5Core 
framework which seems to have these symbols defined.  This is the 
prototype found in the code, are they different from the version of 
Kerberos for the Mac?

extern krb5_error_code krb5_write_message
	KRB5_PROTOTYPE((krb5_context,
		   krb5_pointer,
		   krb5_data *));

Thanks
