I don't have access to a 32-bit machine, would someone mind fixing the test?
A quick fix would be to have this test only run on 64-bit. A better
fix would be to have two tests, one for 64-bit and on for 32-bit. The
latter would use
-- 4294967295 is 2^32, which can be stored in a 64-bit IEEE
floating-point value without
-- loss of precision.
print (D# (word2Double# 4294967295##))
instead of
print (D# (word2Double# 9007199254740992##))
and have the stdout changed to include
4.294967295e9
instead of
9.007199254740992e15
