[xml] Problems building libxml2 when files are read-only (because of source control)

Hi all,

I've been using libxml2 in a project and have hit a snag.  For various
reasons I need to checkin the version of libxml2 I'm using (2.6.22) to
our source control system (ClearCase).   This system keeps files read
only and owned by a privleged user until they are checked out.  I can
create new files but can't modify or even chmod a file that is under
source control without checking it out.

Most configure scripts are fine with this setup, but for libxml2 I'm
having problems.  It wants to modify the following files which are
included in the distribution:

include/libxml/xmlversion.h
python/setup.py
COPYING
libxml2.spec
config.h.in

But it can't do it because the files are readonly.  Anyone have a
solution to this?  (chmod-ing or checking out the files before building
isn't an option)
