    -Wall -Wextra
    # Useful because usually testing floating-point numbers for equality is bad
    -Wfloat-equal
    # Warn if an uninitialized identifier is evaluated in an #if directive
    -Wundef
    # Warn whenever a local variable shadows another local variable, parameter or
    # global variable or whenever a built-in function is shadowed
    -Wshadow
    # Warn if anything depends upon the size of a function or of void
    -Wpointer-arith
    # Warn whenever a pointer is cast such that the required alignment of the target
    # is increased. For example, warn if a char * is cast to an int * on machines
    # where integers can only be accessed at two- or four-byte boundaries
    -Wcast-align
    # Warns about cases where the compiler optimizes based on the assumption that
    # signed overflow does not occur
    # (The value 5 may be too strict, see the manual page)
    -Wstrict-overflow=2
    # Give string constants the type const char[length] so that copying the address
    # of one into a non-const char * pointer will get a warning.
    -Wwrite-strings
    # Warn if any functions that return structures or unions are defined or called
    # add_compile_options(-Waggregate-return)
    # Warn whenever a pointer is cast to remove a type qualifier from the target type*
    -Wcast-qual
    # Warn whenever a switch statement does not have a default case*
    -Wswitch-default
    # Warn whenever a switch statement has an index of enumerated type and lacks a
    # case for one or more of the named codes of that enumeration*.
    -Wswitch-enum
    # Warn for implicit conversions that may alter a value*.
    -Wconversion
    # Warn if the compiler detects that code will never be executed*.
