/* Okay, this is a bit obscure.  The libdb2 configure script doesn't
   detect it, but on Tru64 5.1, netinet/in.h causes sys/bittypes.h to
   be included, and that has a typedef for u_int32_t.  Because the
   configure script doesn't detect it, it causes db-config.h to have a
   #define for u_int32_t, so including db.h and then netinet/in.h
   causes compilation to fail.

   Since gssrpc/types.h includes netinet/in.h, including that first
   will cause the typedef to be seen before the macro definition,
   which still isn't quite right, but is close enough for now.

   A better fix might be for db.h to include netinet/in.h if that's
   where we find u_int32_t.  */
