Quotes and Brackets In Include Directives

[Eric Lemings <eric dot b dot lemings at lmco dot com>]

I always thought that:

#include <string.h>

would include the string.h header in the "system" include path while:

#include "string.h"

would include a different string.h header file in the "local" include
path.

This doesn't seem to be the case in gcc-3.0.1 at least.  The first form
is including the local version rather than the system version of the
string.h header.  This never happened before 3.0.1.  Is this new
behavior?  How do I distinguish the two header files?

Thanks,
Eric.
