I did some more sifting and found a way to get an error output from the shader
compiler.
I hacked it into the shader manager code...anyway i get:
ERROR: error (#272) Implicit version number 110 not supported by GL3 forward
compatible context
Of course googling this yields no information. I can't even find where to
lookup ANY compiler errors. Hopefully that sheds some light on the problem for
some one.

during my window setup, when I get the rendering context using
wglCreateContextAttribsARB(), if I feed in version 2.1, the shader compiles
with no problem and I see a red triangle. Indeed, selecting version 3.0 or 3.1
also works. 3.2 or 3.3 result in the same error:
Vertex shader failed to compile with the following errors:
ERROR: error(#272) Implicit version number 110 not supported by GL3 forward
compatible context
ERROR: error(#273) 2 compilation errors. No code generated
Is this an issue with my hardware/driver? Or a problem with the shader code? My
driver is up to date. My graphics card (Radeon HD 4870) shipped with OpenGL 3.2
support, so I would at least expect the shader to compile with a version 3.2
context specified...

This is because in OpenGL3.2 and above the version qualifier is necessary. If u
donot specify it, the an implicit version 110 is assumed and so the compiler
generates the errors. To resolve these simply add #version 330 or #version 320
depending on th e version of OpenGL u r targetting.
