FYI: minor mkdir-p.c and idcache.c clean-up

[Jim Meyering]

I've just checked in these changes in both gnulib and coreutils:

2005-06-29  Jim Meyering  <address@hidden>

        * mkdir-p.c (make_dir_parents): Don't apply sizeof to a hard-coded
        type name.  Use the variable name instead.
        * idcache.c (getuser, getuidbyname, getgroup, getgidbyname): Likewise.
