This problem is imminent to mingw's implementation of iostream's 
file-io. You cannot use fseekg()/fputg() with files opened in text-mode.
This is a known problem and I don't expect it to be solved in mingw.

To work around it in octave we need to rethink octave's way to save 
anonymous function handles in ascii format.
I have tried something for in the development branch, which allows this 
test to pass, but it means a small but significant change in the format 
of saving anonymous function handles. This breaks backwards 
compatibility, so I'm not really happy about my approach.

I can post it here to start discussions, though...
