It doesn't know anything about that.

However, it does keep track of intermediate files based on the command used to 
compile the file. So it'll treat the file compiled with 'gcc -c -o out.o 
in.c' as being seperate from 'gcc -c -o out.o in.c -DHAVE_BLAHA_H'. (This 
also means that you can build it twice with different sets of flags and it'll 
work.)

If you'e a HAVE_CONFIG_H person then it'll rebuild in.c whenever config.h 
changes, of course.

If you want a look, there's a very simple application that uses it available 
here:

You want LLgen, not the complete compiler suite. However, there's no 
documentation as yet. (It's not really released.)
