I tried updating this patch but got a long series of compiler errors. I could not clear it up for two reasons:

• There was a recent activity to rename static variables foo as s_foo. Are names like s_t_name and s_c_name intended to be static or just string? This breaks some of the macro expansions in the patch.

• There was also a recent maintenance activity (by me actually) to remove dead code that had been commented out by "#if 0" for years. These included many lines in Range for types other than double. Many of the lines in this patch make similar changes in Range. But it doesn't compile with or without those lines. It's not clear whether the patch intended such definitions to become active or not.

Pls see if you can take a look at the intent behind the code and the patch for the above points.
