If tar can't create intermediate directories due to permission
issues, the resulting message is confusing:
./tar xf gcc.tar gcc-8.3.0/include/obstack.h
tar: Unable to create gcc-8.3.0/include/obstack.h: No such file or directory
(here I have gcc-8.3.0 owned by root and no permissions)
The following patch changes this to:
./tar xf gcc.tar gcc-8.3.0/include/obstack.h
tar: Unable to create gcc-8.3.0/include: Permission denied
tar: Unable to create gcc-8.3.0/include/obstack.h: No such file or directory
okay ? or a better way to do this ?
