Surely the correct approach to this, which does not rely on $HOME
being present is something like this, which is snipped from one
of my programs. Obviously you need to define config and pw somewhere
else.

	/* get the path of the tuxtimerc file */

	pw = getpwuid(getuid());
	config = (char *) malloc(strlen(pw->pw_dir)+12);
	if (config==NULL) {
		fprintf(stderr, "wmtuxtime: unable to allocate sufficent "
			"memory, exiting\n");
		exit(1);
		}
	strcpy(config, pw->pw_dir);
	strcat(config, "/.tuxtimerc");

JAB.
