Add "#pragma diag_pop" after the inclusion of these files. SInce they're sometimes included from other system include files, it may take some digging to realise that this is necessary.

Two include files -- stddef.h and string.h -- each lacked one diag_pop pragma to match the diag_push pragma, which meant that including those files would inadvertently disable certain MISRA warnings.
