 `const' is used on about 561 lines in /usr/include/*.h, 244 lines in
 /usr/include/sys/*.h, ...  It is too late to uglify them all.
 
 <sys/cdefs.h> defines away `const' (and other ANSI-only keywords)
 unless NO_ANSI_KEYWORDS or __GNUC__ is defined.  It is assumed that
 `gcc -traditional' is only used to compile dusty code that uses
 these keywords as normal identifiers.  If your code doesn't have
 such identifiers then you can easily define away the identifiers
 directly by compiling with `gcc -traditional -Dconst='.
