/*
* features.h -- predefined symbols and &features
*
* This file consists entirely of a sequence of conditionalized calls
* to the Feature() macro. The macro is not defined here, but is
* defined to different things by the the code that includes it.
*
* For the macro call Feature(guard,symname,kwval)
* the parameters are:
* guard for the compiler's runtime system, an expression that must
* evaluate as true for the feature to be included in &features
* symname predefined name in the preprocessor; "" if none
* kwval value produced by the &features keyword; 0 if none
*
* The translator and compiler modify this list of predefined symbols
* through calls to ppdef().
