H A Dmkdir.cdiff 24524 Tue Apr 01 21:46:22 MST 1997 mpp Fix several problems with mkdir:

1) Fix mkdir -p to exit with the proper exit status and issue an error
message if it was unable to create all of the specified directories
and they did not previously exist. POSIX says:

The mkdir utility shall exit with one of the following values:

0 All the specified directories were created successfully or the
-p option was specified and all the specified directories now
exist.

E.g.

% mkdir -p /var/mkdir
mkdir: /var/mkdir: Permission denied

% touch /tmp/file
% mkdir -p /tmp/file/dir
mkdir: /tmp/file: Not a directory

Previously the above examples would exit with a zero exit status
and no error message. Something like the following run as a
normal user will still not produce an error:

% id
uid=629(mpp) gid=629(mpp)....
% mkdir -p /usr/local/etc
% ls -ld /usr/local/etc
drwxr-xr-x 4 bin bin 512 Dec 26 14:55 /usr/local/etc/

2) Cleaned up the mode handling to be more efficient when multiple
directories are being created.

3) Fixed a problem where directories could be created with the wrong mode
if the the -p option was specified and the build() routine returned
and error. It would leave the umask set incorrectly at this point.

4) Removed an unused variable.

Closes PR# 2304.
