Comment (by eschnett):

 SIZEOF_POINTER is a configuration variable that the user has to set when
 cross-compiling, i.e. when Cactus cannot determine the pointer size
 automatically. We should not use it. We should probably use SIZEOF_CHAR_P,
 which is set in the call AC_CHECK_SIZEOF(char *, $SIZEOF_POINTER). I
 assume that autoconf converts "char *" automatically into the string
 "CHAR_P". AC_CHECK_SIZEOF probably also marks this variable (namely
 SIZEOF_CHAR_P) as one of the variables that is substituted. It should be
 expanded in make.config.defn.in.

 If not, then the command to explicitly mark a variable for substitution is
 AC_SUBST; this is used in many places. The actual substitution happens at
 the end of configure.in in the call to AC_OUTPUT. cctk_Config.h is
 probably treated specially; the fact that it should also be autogenerated
 is probably declared via AC_CONFIG_HEADER in the very beginning.
