Constify get_exec_file

Browse Source 
I noticed that get_exec_file could return a "const char *".  This
patch implements this change.

I couldn't build all the code -- but I did build Linux native and a
mingw cross.

Consequently, the NTO code has a hack, where it casts away const.  I
think this can be removed, but that required more work there, and
since I couldn't compile it, I felt it best not to try.

Let me know what you think.
