Isometric surface sample broken for Mac OpenGL target

Original reporter: binarycrusader

When loading the SampleBrowser (built from hg 1.8 branch) the following error is seen on the console:

Problem parsing the following Cg Uniform: '@TMP29'.

Problem parsing the following Cg Uniform: '@TMP29' in file Ogre/IsoSurf/TessellateTetrahedraGS_CG

The parsing error is ignored, so the isometric surface sample shows up as a volumetric cube of some sort of point cube. (See attached screenshot.)

I traced this down to this bit in mainGS():

//Uber-compressed version of the edge table.
unsigned int edgeListHex[] =
{0x0001cde0, 0x98b08c9d, 0x674046ce, 0x487bc480,
0x21301d2e, 0x139bd910, 0x26376e20, 0x3b700000};

I verified it was this variable declaration by moving it up to the top of isosurf.cg where other uniforms are declared, which changed the error to:

Problem parsing the following Cg Uniform: 'edgeListHex' in file Ogre/IsoSurf/TessellateTetrahedraGS_CG

My guess at the moment is that my system doesn't support an array of unsigned int as arrays of other data types seem to work just fine.

Here's the relevant info to make that determination I think:
