    Dear Paul,

thanks for the prompt response. Your patch really solved the problem!

file pointer" and I am fairly confident the problem is simply that we are not 
testing the return from sys_lseek() correctly.  The result is that the large 
file offset (>2GB) is being interpreted incorrectly by BLCR as a negative 
value indicating an error.

this resolves the problem.
