hello
I'm using MQX 4.2.0.2 run on FRDM-K64F.
And build MQX using KDS3.0
I import the below 4 original MQX project into KDS,
and build them in release mode as the following.
・bsp_frdmk64f
・psp_frdmk64f
・rtcs_frdmk64f
・shell_frdmk64f
build log of [bsp_frdmk64f] and [psp_frdmk64f] is well.
But [rtcs_frdmk64f] and [shell_frdmk64f] have some warning.
Details are as follows.
[rtcs_frdmk64f] build warning log:

Should I ignore these warnings or fix them?
If need to fix, can someone provide an official(NXP) amendment?
Thanks.
