What are you trying to do, exactly? libtar will help you if you are writing a C program to fiddle with tar files (have never used it, just found on google). And you can create a tar file filled with nothing but empty directories. I tried on Solaris 10, and it didn't give any problems.

tar_extract_all(3)						  C Library Calls						tar_extract_all(3)

NAME
tar_extract_all, tar_extract_glob, tar_append_tree - high-level tar archive manipulation functions SYNOPSIS
#include <libtar.h> int tar_extract_all(TAR *t, char *prefix); int tar_extract_glob(TAR *t, char *globname, char *prefix); int tar_append_tree(TAR *t, char *realdir, char *savedir); VERSION
This man page documents version 1.2 of libtar. DESCRIPTION
The tar_extract_all() function extracts all files from the tar archive associated with the TAR handle t into the path named by the prefix argument. The tar_extract_glob() function extracts all files matching the given glob pattern from the tar archive associated with the TAR handle t into the path named by the prefix argument. The tar_append_tree() function appends all files from the directory tree named by realdir to the tar archive associated with the TAR handle t. The pathnames stored in the tar archive are modified by replacing realdir with savedir, so that the files will be extracted into savedir. RETURN VALUES
On successful completion, these functions will return 0. On failure, they will return -1 and set errno to an appropriate value. ERRORS
These functions will fail under the same conditions that the tar_skip_regfile(), tar_extract_regfile(), opendir(), lstat(), or tar_append_file() functions fail. SEE ALSO
