        * COPYING, README, Makefile.in, configure.in: New files.

        * doschk.c: Inserted copyright notice and usage in comments. 
        Reformatted through `indent -gnu'.

        * doschk.c (xmalloc): New function. 
        (alloc_end, fill_ent, display_problems): Use it instead of malloc.

        * doschk.c (fill_ent): If ent->path is allocated 0 bytes, reassign
        pointer to fixed string instead of setting first byte to '\0'.

        * doschk.c (main): Return 0.
