-Wglobal-constructors  # warn on declare global or static variables with dynamic constructors
-Wmisleading-indentation # warn if indentation implies blocks where blocks do not exist
-Wmissing-noreturn # warn about functions that might be candidates for [[noreturn]]
-Wpacked # warn if a structure is given the packed attribute, but the packed attribute has no effect on the layout or size of the structure
-Wpointer-arith # warn on pointer arithmetic
-Wundef # warn if an undefined identifier is evaluated in an #if directive

GCC_WARNINGS
-Wdisabled-optimization # warn if a requested optimization pass is disabled. often, the problem is that your code is too big or too complex
-Wfloat-equal # warn on comparing floating point with == or !=
-Wglobal-constructors  # warn on declare global or static variables with dynamic constructors
-Winvalid-pch # warn if a precompiled header is found in the search path but cannot be used
-Wmisleading-indentation # warn if indentation implies blocks where blocks do not exist
-Wmissing-format-attribute # Warn about function pointers that might be candidates for format attributes
-Wmissing-include-dirs # warn if a user-supplied include directory does not exist
-Wmissing-noreturn # warn about functions that might be candidates for [[noreturn]]
-Wpacked # warn if a structure is given the packed attribute, but the packed attribute has no effect on the layout or size of the structure
-Wpointer-arith # warn on pointer arithmetic
-Wredundant-decls # warn if anything is declared more than once in the same scope, even in cases where multiple declaration is valid and changes nothing
-Wundef # warn if an undefined identifier is evaluated in an #if directive
