A bug in mingw's libc for strtoull() that parses "0x" incorrectly (the
correct parse is "0" with the endptr pointing to 'x', and NOT pointing
beyond x).  Also a weakness in our testsuite - many of the tests are not
asserting sane values of err, or whether res is left unchanged on error.

I'm working on a patch now that I have more awareness of what's going on...
