TR 13/09/99: disabled use of MKDIRFLAGS until it also works for NT
This means either
- we make sure to always use the bash's mkdir command (which accepts
option '-p')
- call the dos shell with MKDIRFLAGS set to an empty string
- use the POSIX mkdir routine
The disadvantage for calling mkdir without '-p' under UNIX is now
that we can always create one subdirectory only which needs to be
relative to an existing directory.
