Or in boost::wave library.

Why I need to use it?

1. To remove limitation on "#include" directive.
2. It can be use for conditional shader compilation

This is not exactly the best way to solve the "include" limitation. The right 
way to do it would be to make a reentrant parser.
Since the basic structure of the parser allows for merging data from parsed 
files, supporting "include" shouldn't require all that much work. So I do 
intend to make it happen relatively soon.

I'm not entirely sure what you mean by your second point though. Do you mean 
ifdef'ing "program" blocks?

About 2nd point - yes. Sometime it may be found very helpfull. And it was heavy 
use in one of my past projects.
