    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"'.
