        Hi,

 As discussed in the debian-policy@ thread at:
    <http://lists.debian.org/debian-policy/2005/09/threads.html#00031>
 I propose the following changes to the Debian Policy to:
 - exceptionally permit not using -fPIC under i386 in CPU intensive
   libraries,
 - document why -fPIC is required in most cases,
 - permit building of static libraries with -fPIC (I don't think this
   has any reason to be forbidden, does it?)

 At all rates, since I'm not a native speaker and because it is my first
 policy patch, I request review and fixes to the debian-policy@ readers.

   Bye,

Debian Release: 3.1
Architecture: i386 (i686)
Kernel: Linux 2.6.9-1-k7

-	  The shared version of a library must be compiled with
-          <tt>-fPIC</tt>, and the static version must not be. In other
-          words, each source unit (<tt>*.c</tt>, for example, for C files)
-          will need to be compiled twice.
+          In the general case, the shared version of a library must be compiled
+          in a way permitting its runtime memory copy to be shared among
+          processes using it.  This requirement is meant to reduce the memory
+          footprint of applications in Debian as a whole.  For example, with
+          the ELF format and the GCC compiler, this is achieved by using the
+          <tt>-fPIC</tt> flag.  As a special exception, some CPU intensive
+          libraries might be compiled without -fPIC under i386 only; this is
+          because currently only i386 really benefits of and has support for
+          binaries compiled without -fPIC.
+
+          This requirement does not apply to the static version of the library.
+          The static version is usually built separately, without -fPIC.
