gcc

  -w  Inhibit all warning messages.

 -Wall
           All of the above -W options combined.  This enables all the warnings
           about constructions that some users consider questionable, and that
           are easy to avoid (or modify to prevent the warning), even in con-
           junction with macros.  This also enables some language-specific warn-
           ings described in C++ Dialect Options and Objective-C and
           Objective-C++ Dialect Options.

把“几乎”所有warning都显示出来。
