	Yes, I've had that problem with some programs, too.

	I think we should do 1).  A program should not have any
function prototype which is in the libc; it should just include <string.h>
instead.  We had a similar problem with `errno', do you remember?

	And... we have a similar problem with many other functions.
For example, this program fails to compile with glibc-2.0 (the current
one used with i386), even without -O2:
#include <ctype.h>
extern int isalnum(int);
int main() {}

	So I think we can't do 2) or 3).  1) is the best choice.  And
I think you should would submit a bug report against the package with
that prototypes.
