   178 Makefile Variables
       
   179 ==================
       
   180 
       
   181 Some Makefile variables are reserved by the GNU Coding Standards for
       
   182 the use of the "user" - the person building the package. For instance,
       
   183 CXX and CXXFLAGS are such variables, and have the same meaning as
       
   184 explained in the previous section. These variables can be set on the
       
   185 command line when invoking `make' like this:
       
   186 `make [VARIABLE=VALUE]...'
       
   187 
       
   188 WARNINGCXXFLAGS is a non-standard Makefile variable introduced by us
       
   189 to hold several compiler flags related to warnings. Its default value
       
   190 can be overridden when invoking `make'. For example to disable all
       
   191 warning flags use `make WARNINGCXXFLAGS='.
       
   192 
       
   193 In order to turn off a single flag from the default set of warning
       
   194 flags, you can use the CXXFLAGS variable, since this is passed after
       
   195 WARNINGCXXFLAGS. For example to turn off `-Wold-style-cast' (which is
       
   196 used by default when g++ is detected) you can use
       
   197 `make CXXFLAGS="-g -O2 -Wno-old-style-cast"'.
