 This is not about autotools. This particular code fragment does not rely on autotools. It's just the following text in .h file:
--- cut ---
#ifndef __u_char_defined
typedef __u_char u_char;
typedef __u_short u_short;
typedef __u_int u_int;
typedef __u_long u_long;
typedef __quad_t quad_t;
typedef __u_quad_t u_quad_t;
typedef __fsid_t fsid_t;
# define __u_char_defined
#endif
#ifndef __daddr_t_defined
typedef __daddr_t daddr_t;
typedef __caddr_t caddr_t;
# define __daddr_t_defined
#endif
--- cut ---

 Looks like this should work for some hypothetical system which doesn't have things like u_char etc. Here __u_char and friends appear to be own versions, defined somewhere by glibc code itself. This code causes 'type redefinition' error because we actually have u_char but don't have accompanying indicator.
