-- Removed m4/optimizations.m4, and along with it, AC_OPTIMIZATIONS.
-- Stripped down, cleaned up, and merged the former together with other compiler
   characteristic checks.
-- Do not set any optimization flags into CFLAGS.  Update all Makefile.am's with
   proper AM_CFLAGS, AM_CPPFLAGS, AM_LDFLAGS, etc. to set up optimization flags,
   usually from DEFAULT_OCFLAGS.
-- Start cleaning up CFLAGS/CPPFLAGS stuff in Makefile.am's all over the place.
-- Correct a number of places where CFLAGS itself was being mangled in
   Makefile to on-the-fly adjust optimizations to work around compiler bugs.
   This stuff is now done correctly.
-- The run of automake from autogen.sh is now clean of warnings.
-- Cleaned out some (now) dead macros from m4/_xine.m4
-- Mac OS X intel builds out-of-the-box now -- dropped optimization on
   post/deinterlace/plugins/kdetv-greedyh to O1_CFLAGS.
-- OBJCFLAGS is now getting set correctly everywhere that it needs to be
-- Various other miscellaneous cleanups all over

Detection of libxdg-basedir presence is now done through pkg-config, and to use
the external copy you have to have at least 0.1.3 because previous versions contain
one bug that causes /usr/share to become /usr/sharee.

Remove the patch, no differences from the original are present at this time.

Also add a diff from the original sources and add it to the distribution.

The libxdg-basedir project, developed by Mark Nevill, implements
a simple way to use the XDG_* variables used to define the paths
for the XDG Base Directory Specification (0.6).

As I was going to reinvent the wheel, I prefer to import this
library that was already written, hoping it will continue being
developed.
