Lots of compilation errors

I'm trying to compile the program

#include <cassert>
#include <GL/glew.h>
#include <GL/glut.h>
#include <oglplus/all.hpp>

int main()
{
  return 0;
}

and I'm getting loads of compilation errors. These are, broken down by the individual headers:

context.hpp - quite a lot of errors of the form

implement/oglplus/enums/pixel_parameter_type.ipp:39:38: error: 'PackCompressedBlockWidth' is not a member of 'oglplus::enums::PixelParameter'
 struct EnumAssocType<PixelParameter, PixelParameter::PackCompressedBlockWidth>
                                      ^
implement/oglplus/enums/pixel_parameter_type.ipp:39:38: error: 'PackCompressedBlockWidth' is not a member of 'oglplus::enums::PixelParameter'
implement/oglplus/enums/pixel_parameter_type.ipp:39:78: error: template argument 2 is invalid
 struct EnumAssocType<PixelParameter, PixelParameter::PackCompressedBlockWidth>

Looking at the code, it seems that PackCompressedBlockWidth is declared in pixel_parameter_def.ipp, but only if GL_PACK_COMPRESSED_BLOCK_WIDTH is defined, whereas it's defined in pixel_parameter_type.ipp no matter what. So if GL_PACK_COMPRESSED_BLOCK_WIDTH isn't defined, which I guess it isn't on my setup, you get compilation errors. If you surround the definitions with #if defineds the way the declarations are the errors disappear.

Commenting out the offending OGLPLUS_FAKE_USE(size) lines fixes the problem. Since they're apparently only in there to stop the compiler complaining I'm not sure why they're there.

No idea what the "requires template<>" error means, but I guess it's down to the fact the braces are getting imbalanced somewhere.

Not sure what this one's about.

Don't know what this one's about either. Sorry about the huge bug report!
