What is the difference between Wmissing-prototypes and Wmissing-declarations?
-Wmissing-prototypes (C and Objective-C only)
Warn if a global function is defined without a previous prototype
declaration. This warning is issued even if the definition itself provides a
prototype. The aim is to detect global functions that fail to be declared in
header files.
-Wmissing-declarations
Warn if a global function is defined without a previous declaration.
Do so even if the definition itself provides a prototype. Use this option to
detect global functions that are not declared in header files. In C++, no
warnings are issued
for function templates, or for inline functions, or for functions in
anonymous namespaces.
They seem exactly the same thing!
