parse-datetime test failure

[Bruno Haible via Gnulib discussion list]

Hi Pádraig,

The new unit test fails on 32-bit Cygwin and on native Windows:

../../gltests/test-parse-datetime.c:280: assertion 'parse_datetime (&result, p, 
NULL)' failed
../../gltests/test-parse-datetime.c:283: assertion 'parse_datetime (&result2, 
p, NULL)' failed
../../gltests/test-parse-datetime.c:285: assertion 'result.tv_sec == 
result2.tv_sec' failed
FAIL test-parse-datetime.exe (exit status: 1)
