'-Winline' is documented here: [1] You asked the compiler "tell me when your heuristics have the effect that the function is not inlined, as expected", and the compiler told you. > or can the inline > functions of gl_xlist.h be implemented in a way so that this warning cannot > show up? If we were to add an __attribute__ ((__always_inline__)) to the declaration of 'gl_list_add_last', it would have the effect to override GCC's heuristics. In other words, it would generate code that is worse than the code that it generates by default. I don't find this desirable. > Is there a way to suppress this warning using Gnulib Well, just don't specify '-Winline', if you are not interested in the nitty gritty details of the generated code. The Gnulib module 'manywarnings' [2] helps you eliminate warning options that produce clutter.
