If you're adding fields to the entries file anyway, with the aim of
independence from mtimes, I suggest an inode number field too. (Yes,
apr makes an inode number available on win32 as well as unix). The
idea is to require the inode number to match, as well as the mtime,
when deciding to skip the file compare.

This prevents a misunderstanding with 'svn update foo1 foo2; mv foo1
foo2'. (The 'svn update' will give foo1 and foo2 approximately the
same mtime, and 'mv' does not change it, so at present this will not
detect that foo2 has changed.)
