	STDCXX-756
	* tests/src/printf.cpp (_rw_fmtexpr): Handled malloc(() failure to
	silence HP aCC 6 warning 20200: Potential null pointer dereference.

	(_rw_pvasnprintf, rw_sprintf, rw_snprintf): Cast operand to a wider
	type before adding to it to silence HP aCC remark 4298: addition
	result could be truncated before cast to bigger sized type.
	(_rw_fmtstr): Commented out redundant extern keyword to silence
	the annoying HP aCC 6 remark 4244: extern storage class used with
	a function definition.
	(_rw_quotechar): Made use of the new _RWSTD_UWCHAR_INT_T type to
	silence HP aCC 6 remark 4248: comparison of unsigned integer with
	a signed integer.
	(_rw_fmtfloating): Replaced a for loop with an equivalent call to
	strlen() to silence another useless HP aCC remark, 4315: for loop
	without body, did you insert an extra ';'?
