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