[xemacs-hg @ 2005-08-01 16:28:18 by darrylo] On some (64-bit) systems, sizeof(int) != sizeof(long), and this can cause crashes because in-use lisp objects can get prematurely gc'd (and 0xdeadbeef'd). This occurs because the memory_description for the Gap_Array structure incorrectly describes some members as XD_INT's (32-bit objects), when they should actually be XD_ELEMCOUNT's and XD_BYTECOUNT's (both 64-bit objects), as that is how they are declared in the structure.

test -r $2

cmp $1 $2 > /dev/null
then
echo $2 is unchanged
rm -f $1
else
mv -f $1 $2
fi

mv -f $1 $2
