There are more testcase which need fixing. The patch I submitted only
covers the simple ones, and I haven't even looked at any of the C++ ones
yet. Simply skipping the test case leaves the possibility of silent
regressions on 16-bit targets, which are already lacking testing.

How about guarding each problematic line with something like
#if INT_MAX >= 0x7fffffff
... original code here ...
#else
... modified code with long or int_least32_t here ...
#endif
? Failing that, I prefer to go with Richard's second suggestion of creating a
duplicate, fixed test case for each problematic one, and skipping the
unmodified one on 16-bit targets.
