mkdir-p.c port to Solaris 8 NFS client

[Paul Eggert]

I installed the following to handle a porting problem on Solaris 8.

2005-09-21  Paul Eggert  <address@hidden>

        * mkdir-p.c: Change "#if HAVECONFIG_H" to "#ifdef", for
        compatibility with latest gnulib.
        (ENOSYS): Define to EEXIST if not defined.
        (make_dir_parents): Treat ENOSYS like EEXIST.
