Import of CCS3 project in CCS4 causes build failure with std.h not found

Hello CCS champs!

Import of CCS3 project in CCS4 causes build failure with std.h not found

Is there a permanent patch/fix for this in CCS?

We tried  a workaround of replacing

#include "std.h"

with

#include <xdc/std.h>

best regards
