        * configure.in: Checking for __int64 as possible candidate for
        the SCM_I_GSC_T_INT64 define.

        * threads.h: Redefined scm_getspecific() and scm_setspecific()
        to be functions instead of macros.

        * threads.c: Conditionalized inclusion of <sys/time.h> and
        <unistd.h>.
        (scm_getspecific, scm_setspecific): Made these two function
        real part of the API.

        * posix.c (s_scm_putenv): Added some code to make a
        (putenv "FOO="), i.e. setting an empty string, work also on
        Win32 systems.  Thanks to Kevin Ryde for the proposal.
