My bad here, I replaced beforehand the occurrences of fpos_t with
posix_fpos_t after grepping in HelenOS headers. I forgot to
take that out to reproduce the original error. I'm sorry.
This is actually the original error:
contrib/tools/pngfix.c:868:19: error: field 'data_pos' has incomplete type
fpos_t data_pos; /* Position of first byte of chunk data */
^
contrib/tools/pngfix.c:1550:19: error: field 'chunk_data_pos' has
incomplete type
fpos_t chunk_data_pos; /* Position of first byte of chunk data */
^
contrib/tools/pngfix.c: In function 'zlib_check':
contrib/tools/pngfix.c:2615:11: error: storage size of 'start_pos' isn't known
fpos_t start_pos;
^
I don't really get what is wrong, my guess is some header is missing
but I'm not quite sure, stdio.h is included in pngfix.

Yes, I saw that and I replaced fpos_t with _posix_fpos since I thought
the problem was that it couldn't find a declaration
but it looks that there's something else to be done.

I totatlly agree. I already forked it and commited the harbour, the
patch and some notes.
Cheers,
