I don't think that's be possible, because you can even define a
"DEFINE" by command line to gcc, right?
Just changing background for the region between #ifdef to #endif can
be done, though.

An ability similar to this apparently exists in emacs 23
(CVS). Accoridng to the news file, you can make these constructs
"shaded" rather than just invisible. I'm assuming shading really eans
setting them to different foreground/background colours to the main/rest
of the text.

code between '#ifndef' with a different fore/background color

[Rodrigo Canellas]

Hi,

Is is possible to define that a block of code between a '#ifdef XYZ' - 
'#endif', when 'XYZ' is not defined, is displayed with a different 
foreground (or background) font color?

thanks a lot!

I do not think you can do it directly, but if you know emacs lisp you 
could hack hide-ifdef-mode to do it.

If you do that then please tell us how you did it.

See hide-ifdef-shadow (the variable to enable it, and the face of the
same name to customize the fore/background).
