Yes, you're right. Strange, what is the difference between the art of a 
structure member:
- st_blocks:  AC_STRUCT_ST_BLOCKS (not replaced)
- st_blksize: AC_STRUCT_ST_BLKSIZE (replaced) --> 
AC_CHECK_MEMBERS([struct stat.st_blksize])
so that they should be checked in a different way. In the man page they 
are mentioned together:
"Use of the st_blocks and st_blksize fields may be less portable.  (They 
were introduced in BSD.  The interpretation differs between systems, and 
  possibly on a single system when NFS mounts are involved.)"
