opensc builds ok on 64-bit archs with llvm22, but fails on i386:

helpfully, DES_LONG is an unsigned long on i386, but an unsigned int
on other archs:
/usr/include/openssl/des.h:
64 #ifndef DES_LONG
65 /* XXX - typedef to unsigned int everywhere. */
66 #ifdef __i386__
67 #define DES_LONG unsigned long
68 #else
69 #define DES_LONG unsigned int
70 #endif
71 #endif
is this an appropriate fix for now?
