Even if the target = host test shall remain, I would say that the case 
statement is clearer if you use the host.

I'm not sure I understand the rationale, but that's fine if it was 
discussed on the mailing lists.

This was not changed because I used

   : ${enable_largefile=no}

The reason for this change is that the Autoconf test uses 
"$enable_largefile" != 'no', so changing anything the user gives 
(including --enable-largefile= i.e. the empty string) to 'no' is 
undesirable.
