2003-09-24  Dave Brolley  <brolley@redhat.com>

        * frv.cpu (u-commit): New modelling unit for fr500.
        (mwtaccg): Use frv_ref_SI to reference ACC40Sk as an input operand.

Remove test code.

* include/GL/glu.h (gluErrorUnicodeStringWIN): Add macro
function. MSDN suggests using gluErrorUnicodeStringWIN
instead of gluErrorString, as it allows both ANSI and Unicode
error strings.
* include/GL/glu.h (gluErrorUnicodeStringEXT): Make the
returned pointer const for consistency reasons.

* include/GL/glu.h (gluErrorUnicodeStringEXT): Add function.
Function exists in glu32.def but is undocumented on MSDN.
A Google search came up with this declaration.

* include/GL/glu.h: Rewritten from scratch. Started from GLU 1.3
headers from OpenGL Sample Implementation. Windows ships with
GLU 1.2 so some constants and functions were removed. Then some
typedef's and function declarations were reworked to look like
the previous GL/glu.h.
