ARENE_STD_LIBRARY_UNCAUGHT_EXCEPTIONS

#define ARENE_STD_LIBRARY_UNCAUGHT_EXCEPTIONS

A platform support query for testing if __cpp_lib_uncaught_exceptions is defined.

Usage:

#if ARENE_IS_ON(ARENE_STD_LIBRARY_UNCAUGHT_EXCEPTIONS)

The value of this query is determined as follows, in order of precedence:

1. If ARENE_STD_LIBRARY_UNCAUGHT_EXCEPTIONS has been explicitly defined via a -D flag to the compiler or similar:
   • ARENE_ON if it is truthy
   • ARENE_OFF if it is not truthy

1. If __cpp_lib_uncaught_exceptions is defined it is ARENE_ON_BY_DEFAULT

1. Otherwise, it is ARENE_OFF_BY_DEFAULT
