You are right. There is a somewhat funny behavior of the emx library.
If you want to use random file access you should use the binary
mode to access files ("rb"). You opened the file in text-mode ("r"). 
There is a bug in the library documentation. Standard mode for files
should be binary but in reality it is text mode. In binary mode
all goes right, I had problems with this too and asked Kai Uwe Rommel.
He confirmed the bug. Eberhard Mattes knows it too.
