test lseek SEEK_END being ignored after fread

best expressed in python:

filelen = 200
f = open("tst", "wb")
for i in range(filelen):
    f.write(chr(i%256))
f.close()

f = open("tst", "rb")
f.seek(filelen-22)
x = f.read(20)
f.seek(-98, 2)
print (filelen-98), f.tell()

but c version is attached.

from what i can best tell, the lseek(-9, SEEK_END) is just simply... being
ignored! :)

if you comment out the fread, the lseek is successful.
