This is a documentation fix which has already happened, see
http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html .
-Wall
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.
-Wall turns on the following warning flags:

          -Waddress   
          -Warray-bounds (only with -O2)  
          -Wc++0x-compat  
          -Wchar-subscripts  
          -Wimplicit-int  
          -Wimplicit-function-declaration  
          -Wcomment  
          -Wformat   
          -Wmain (only for C/ObjC and unless -ffreestanding)  
          -Wmissing-braces  
          -Wnonnull  
          -Wparentheses  
          -Wpointer-sign  
          -Wreorder   
          -Wreturn-type  
          -Wsequence-point  
          -Wsign-compare (only in C++)  
          -Wstrict-aliasing  
          -Wstrict-overflow=1  
          -Wswitch  
          -Wtrigraphs  
          -Wuninitialized (only with -O1 and above)  
          -Wunknown-pragmas  
          -Wunused-function  
          -Wunused-label     
          -Wunused-value     
          -Wunused-variable  
          -Wvolatile-register-var
