I'm not sure what you were seeing for this.  You added some setting of the
static fileflags variable to 0 for the non-fileflags option case, but that
variable is always 0 when that option is off.  I did change the bit that
initializes F_FFLAGS(file) to ensure that force_changes w/o preserve_fileflags
sets it to 0.  I also made sure that the code that fakes the value into
st_flags sets a 0 if --fileflags is off.

I note that dirname() function expects a non-const string and may potentially
change the buffer, so it can't be used in these syscall functions.  I created a
function that tweaks the path into a buffer and calls make_mutable() on the
result, and then twiddled your new code to make use of it.  I also enhanced
make_mutable() a bit and simplified some of the existing make_mutable() calls.

The result has been checked into the patches git repo.

Thanks!
