How about:

struct BlockData
{
     BlockData(std::sizt_t a_index, const char *a_description) :
         index(a_index), description(a_description)
     { }
     std::sizt_t index;
     const char *description;
};

BOOST_ENUM_VALUES(BlockType_t, BlockData,
     (SampleIfg)(BlockData(0, "Sample Interferogram"))
     (SampleSpec)(BlockData(1, "Sample Spectrum"))
)

or even better for my taste:

BOOST_ENUM_VALUES(BlockType_t, BlockData,
     (SampleIfg)({ 0, "Sample Interferogram" })
     (SampleSpec)({ 1, "Sample Spectrum" })
)

and then you don't even need to constructor of BlockData.

I'm not sure if this compiles, but I hope it does. If it doesn't, can 
you make it work, Frank? If it does, then I guess it's quite nice for 
you, Richard, isn't it?
