 Each program-name variable should come with an options variable that is
 used to supply options to the program.  Append @samp{FLAGS} to the
 program-name variable name to get the options variable name---for
-example, @code{BISONFLAGS}.  (The names @code{CFLAGS} for the C
-compiler, @code{YFLAGS} for yacc, and @code{LFLAGS} for lex, are
-exceptions to this rule, but we keep them because they are standard.)

 If there are C compiler options that @emph{must} be used for proper
 compilation of certain files, do not include them in @code{CFLAGS}.
