Ryan Lortie aba0f0c38b gatomic: introduce G_ATOMIC_LOCK_FREE 
We clean up the detection of if we should do 'real' atomic operations or
mutex-emulated ones with the introduction of a new (public) macro:
G_ATOMIC_LOCK_FREE.  If defined, our atomic operations are guaranteed to
be done in hardware.

We need to use __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 to determine if our
compiler supports GCC-style atomic operations from the gatomic.h header
because we might be building a program against GLib using a different
set of compiler options (or a different compiler) than was used to build
GLib itself.

Unfortunately, this macro is not available on clang, so it has currently
regressed to using the mutex emulation.  A bug about that has been
opened here:

README 

This package contains the reference documentation
for GLib. For more information about Glib,
see:

 http://www.gtk.org

For information about contributing to the
GLib/GTK+ reference documentation project, see:

 http://www.gtk.org/rdp/

The GLib reference documentation is freely redistributable,
see the file COPYING for details.


REQUIREMENTS
============

To build the documentation, you must have the gtk-doc
package installed. To rebuild the template files,
you must have the current version of the GLib
header files installed.


BUILD
=====

First, run configure to generate the makefiles for this
module. There is one option specific to this package

  --with-html-dir=DIR   top of installed HTML documentation tree


The Makefiles for this module define three targets:

 templates:
  
  Scan the headers and merge the results with the current 
  template files

 sgml:

  Generate SGML files using the DocBook DTD from
  the template files

 html:

  Generate HTML from the SGML files.

To build the documentation, do:

 make sgml
 make html

You should only run the 'make templates' step if you
need to regenerate the templates for a more recent
version of the GLib sources.


INSTALLATION
============

 make install
