Provides highlighting for  #ifdef  #ifndef  #else  #endif  blocks, with the ability to mark a symbol as defined or undefined.
Handles nesting of #ifdefs (and #if) as well, but does not handle  #if defined().

Supports vim_ifdef:  modelines and .defines (_defines for win16/win32s) files to specify defined/undefined symbols.

use :Define <keyword>  or  :Undefine <keyword>     to dynamically specify defined or undefined sections.
