Allison Ryan Lortie d0219f2597 GLib: add bounds-checked unsigned int arithmetic 
Add some helpers for builds-checked unsigned integer arithmetic to GLib.
These will be based on compiler intrinsics where they are available,
falling back to standard manual checks otherwise.

The fallback case needs to be implemented as a function (which we do
inline) because we cannot rely on statement expressions.  We also
implement the intrinsics case as an inline in order to avoid people
accidentally writing non-portable code which depends on static
evaluation of the builtin.

For now there is only support for addition and multiplication for guint,
guint64 and gsize.  It may make sense to add support for subtraction or
for the signed equivalents of those types in the future if we find a use
for that.

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
