Tool/software: TI C/C++ Compiler
Using TI's C2000 C Compiler, like this:

Where "stdio.h" is included in the source file, I get these warnings:

Looking at some of the other standard library headers, I've seen these pragmas that are meant to deal with this:
#pragma diag_push
#pragma CHECK_MISRA("-20.1") /* standard headers must define standard names */
#pragma CHECK_MISRA("-20.2") /* standard headers must define standard names */
#pragma CHECK_MISRA("-19.7") /* macros required for implementation */
#pragma CHECK_MISRA("-19.10") /* need types as macro arguments */
These are not present in "stdio.h". If I add them manually, I can disable these warnings.
Is this an oversight or what's the rationale for leaving these out of that particular header?
I didn't check all of the other standard header files, but "stdio.h" is definitely affected.
