------- Comment #5 from pinskia at gcc dot gnu dot org 2007-07-31 21:49 ------- http://gcc.gnu.org/onlinedocs/gcc-4.2.1/gcc/Warning-Options.html -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 conjunction with macros. This also enables some language-specific warnings described in C++ Dialect Options and Objective-C and Objective-C++ Dialect Options.
And: http://gcc.gnu.org/onlinedocs/gcc-4.2.1/gcc/C_002b_002b-Dialect-Options.html Under: The following -W... options are not affected by -Wall. .... -Woverloaded-virtual (C++ only) Warn when a function declaration hides virtual functions from a base class. For example, in: struct A { virtual void f(); }; struct B: public A { void f(int); }; the A class version of f is hidden in B, and code like: B* b; b->f(); will fail to compile. -- pinskia at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32934
