Carl Worth 285c9392ad glsl/glcpp: Add (non)-support for ++ and -- operators
These operators aren't defined for preprocessor expressions, so we never
implemented them. This led them to be misinterpreted as strings of unary
'+' or '-' operators.

In fact, what is actually desired is to generate an error if these operators
appear in any preprocessor condition.

So this commit looks like it is strictly adding support for these
operators. And it is supporting them as far as passing them through to the
subsequent compiler, (which was already happening anyway).

What's less apparent in the commit is that with these tokens now being lexed,
but with no change to the grammar for preprocessor expressions, these
operators will now trigger errors there.

A new "make check" test is added to verify the desired behavior.

This commit fixes the following Khronos GLES3 CTS test:

	invalid_op_1_vertex
	invalid_op_1_fragment
	invalid_op_2_vertex
	invalid_op_2_fragment

Last updated: 21 June 2013


Quick Start
----- -----

Windows drivers are build with SCons.  Makefiles or Visual Studio projects are
no longer shipped or supported.

Run

  scons osmesa mesagdi

to build classic mesa Windows GDI drivers; or

  scons libgl-gdi

to build gallium based GDI driver.

This will work both with MSVS or Mingw.


Windows Drivers
------- -------

At this time, only the gallium GDI driver is known to work.

Source code also exists in the tree for other drivers in
src/mesa/drivers/windows, but the status of this code is unknown.

Recipe
------

Building on windows requires several open-source packages. These are
steps that work as of this writing.

- install python 2.7
- install scons (latest)
- install mingw, flex, and bison
- install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs
  get pywin32-218.4.win-amd64-py2.7.exe
- install git
- download mesa from git
  see http://www.mesa3d.org/repository.html
- run scons

General
-------

After building, you can copy the above DLL files to a place in your
PATH such as $SystemRoot/SYSTEM32.  If you don't like putting things
in a system directory, place them in the same directory as the
executable(s).  Be careful about accidentially overwriting files of
the same name in the SYSTEM32 directory.

The DLL files are built so that the external entry points use the
stdcall calling convention.

Static LIB files are not built.  The LIB files that are built with are
the linker import files associated with the DLL files.

The si-glu sources are used to build the GLU libs.  This was done
mainly to get the better tessellator code.

If you have a Windows-related build problem or question, please post
to the mesa-dev or mesa-users list.
