Not completely.  "const" can usually be defined away by compiling with
-Dconst=.  <sys/cdefs.h> has some support for sort of the reverse of
this -- it defines away "const" and some other keywords by default if the
compiler is "gcc -traditional", but compiling with -DNO_ANSI_KEYWORDS
prevents this.  Very old programs may have variables named "const" and
defining away "const" would just break them, but defining away "const"
usually works for K&R programs.
