3# Tests for the variable modifiers ':On', which returns the words, sorted in
4# ascending numeric order, and for ':Orn' and ':Onr', which additionally
5# reverse the order.

10# This list contains only 32-bit numbers since the make code needs to conform
11# to C90, which does not necessarily provide integer types larger than 32 bit.
12# Make uses 'long long' for C99 or later, and 'long' for older C versions.

14# To get 53-bit integers even in C90, it would be possible to switch to
15# 'double' instead, but that would allow floating-point numbers as well, which
16# is out of scope for this variable modifier.
