-By default, 'gawk' uses the double-precision floating-point values
+ WARNING: As of version 5.2, arbitrary precision arithmetic in
+ 'gawk' is _deprecated_. It will be removed from 'gawk' in 2024.
+
+ MPFR support is deprecated because its inclusion was a mistake. It

supplied by the hardware of the system it runs on. However, if it was
compiled to do so, and the '-M' command-line option is supplied, 'gawk'
