Each of the CONFIG_THINGY options (which are checked with #ifdef or #ifndef) 
now have an ENABLE_THINGY defined as well (which is always defined, as 0 or 
1), which can be used in normal if(ENABLE_THINGY) tests that get optimized 
out by the compiler when it's set to 0.  This way you can use normal C code 
rather than preprocessor directives to handle configuration symbols.

You can also go "#if ENABLE_THINGY" in place of an #ifdef, so you can use the 
one symbol everywhere.

Unfortunately, gcc's preprocessor isn't smart enough to chop out static 
functions that never get called, so you still need to #if those out.

True, but the original setterm does more than this.  (And not just redoing 
terminal screen blanking, which is also just another funky escape sequence 
sent to the kernel, but resetting the default color so that when you esc[0m 
you get the new default color back...)

Strangely, that only seems to work on linux kernel controlled text termals and 
not on konsole, so probably it's not important...

You too,
