I don't know anything about the Windows-specific details here,
but the --with-blocksize option looks fine, and it works for me:

regression=# show block_size;
 block_size 
------------
 16384
(1 row)

(Worth noting here is that a lot of our regression tests fail
at non-default blocksizes, because plans change, or rows no
longer need toasting, or the like.)

I think you must be connecting to the wrong server.
