I have an application where I'm building and manipulating a stack of
variable-length strings.  I've set up a linked list of nodes, each one
declared as follows:

struct node {
	struct node* next;
	char	string[];
} *nodeptr;

When I know how long the string is I'm pushing onto the stack, I say:

	nodeptr = malloc(strlen(data)+5);

to cover the struct node* and terminating NULL, and then simply

	strcpy(nodeptr->string, data);

The only problem I have is with compilation:  I get a warning about the
zero-length element "string".  I'd like to find out the "correct" way to
do this.  I'll be glad to summarize any Emailed responses, of course.

Thanks,		Charles Green		charles%c3pe@decuac.dec.COM
