Patch from SF bug #473150: configure weaknesses on HP-UX (Michael Piotrowski)

    1. configure doesn't handle HP-UX release numbers
    (e.g., B.11.00), resulting in MACHDEP = "hpuxB".

    2. After checking for wchar.h, configure doesn't
    include it when checking the size of wchar_t.

    (Python 2.2b1 on HP-UX 11.00)
