  Yes ftell have bugs, but, can you use the binary mode?, if you really need to 
be seeking in a text file open it in binary mode you'll avoid problems of ftell 
(even the comercial packages have some troubles) and you'll get much (really 
much) more speed. Some common problem with the ftell is that an advance in the 
file may be reported as a retrocess by ftell if you make arithmetic with the 
file pointers, so you are limited in the use of ftell (this thing can be 
observed in BC++ 3.1 and DJGPP v2.0 22 Feb 96).
