I've tested on another machines with Cygwin v1.7.11 and v1.7.25. And it
worked. That`s Ok.
Also, I've run ./cygwin-mktime-bug.exe in CMD, and SUPRISINGLY it
worked, but when I run the SAME `cygwin-mktime-bug.exe` in `bash -l -i` it does not!
Ha-ha! After I've wrote text above, I've tested run `cygwin-mktime-bug.exe`
in `bash`, `bash -i`, `bash -l` AND(!) it worked well in first TWO
cases (`bash` & `bash -i`), and DOES NOT in `bash -l`.
How can it be? 8-O
