This checker guards against using some vulnerable C functions which are mentioned in MSC24-C in obsolescent functions table.
The checker warns only if __STDC_LIB_EXT1__ macro is defined and the value of __STDC_WANT_LIB_EXT1__ macro is 1 in this case it suggests the corresponding functions from Annex K instead the vulnerable function.
