Upgrade unifdef:
* It now knows about the existence of #elif which would have caused it to produce incorrect results in some situations. * It can now process #if and #elif lines according to the values of symbols that are specified on the command line. The expression parser is only a simple subset of what C allows but it should be sufficient for most real-world code (it can cope with everything it finds in xterm). * It has an option for printing all of the symbols that might control #if processing. The unifdefall script uses this option along with cpp -dM to strip all #ifs from a file. * It has much larger static limits. * It handles nested #ifs much more completely. There have also been many style improvements: KNF; ANSI function definitions; all global stuff moved to the top of the file; use stdbool instead of h0h0bool; const-correctness; err(3) instead of fprintf(stderr, ...); enum instead of #define; commentary. I used NetBSD's unifdef as the basis of this since it has received the most attention over the years. PR: 37454 Reviewed by: markm, dwmalone Approved by: dwmalone (mentor) MFC after: 3 weeks
