-# types.pl - find recommended type definitions for digits and words
-#
-# This script scans the Makefile for the C compiler and compilation
-# flags currently in use, and using this combination, attempts to
-# compile a simple test program that outputs the sizes of the various
-# unsigned integer types, in bytes. Armed with these, it finds all
-# the "viable" type combinations for mp_digit and mp_word, where
-# viability is defined by the requirement that mp_word be at least two
-# times the precision of mp_digit.
-#
-# Of these, the one with the largest digit size is chosen, and
-# appropriate typedef statements are written to standard output.
