Wchar-subscripts Warn when an array subscript has type char.
This is a common cause of error, as programmers
often forget that this type is signed on some
machines.
Wcomment Warn whenever a comment-start sequence /*
appears in a comment.
Wconversion Warn when a prototype causes a type conversion
different from what would happen to the same
argument in the absence of a prototype. This
includes conversions of fixed point to floating
and vice versa, and conversions changing the
width or signedness of a fixed point argument,
except when these are the same as the default
promotion.
Werror Make all warnings into errors.
Wformat Check calls to printf and scanf, etc., to make
sure that the arguments supplied have types
appropriate to the specified format string.
Wid-clash-
len
Warn whenever two distinct identifiers match in
the first
len
characters. This may help you
prepare a program that compiles with certain
obsolete compilers. There is no
[no-] form of
this option.
Wimplicit Warn when a function is used without being
explicitly declared.
Wmissing-braces Warn when an initializer is not completely
enclosed within braces.
