[PATCH v2] git-count-objects: Fix a disk-space under-estimate on Cygwin

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

On Cygwin, the st_blocks field in 'struct stat' counts in blocks
of st_blksize bytes. At least on NTFS, the st_blksize field is
not 512 bytes, as required by the code, which leads to an under
estimate of the disk-space used.

Setting the build variable NO_ST_BLOCKS_IN_STRUCT_STAT, switches
to an algorithm that only uses the st_size field to compute the
disk-space estimate.
