Irrelevent, since we always go through the DOS filesystem calls.
Nothing in a djgpp application needs to worry about the physical
layout of a file on disk.

There is an st_size member, but it is in bytes, not blocks.
<sys/vfs.h> has a statfs structure that returns physical blocksize and
number of physical blocks on each drive.
