instance, @option{-Wno-yacc} will hide the warnings about
POSIX Yacc incompatibilities.
+@item -Werror[=@var{category}]
+@itemx -Wno-error[=@var{category}]
+Enable warnings falling in @var{category}, and treat them as errors. If no
+@var{category} is given, it defaults to making all enabled warnings into errors.
+
+@var{category} is the same as for @option{--warnings}, with the exception that
+it may not be prefixed with @samp{no-} (see above).
+
+Prefixed with @samp{no}, it deactivates the error treatment for this
+@var{category}. However, the warning itself won't be disabled, or enabled, by
+this option.
+
+Note that the precedence of the @samp{=} and @samp{,} operators is such that
+the following commands are @emph{not} equivalent, as the first will not treat
+S/R conflicts as errors.
+
+@example
+$ bison -Werror=yacc,conflicts-sr input.y
+$ bison -Werror=yacc,error=conflicts-sr input.y
+@end example
++
+ @item -f [@var{feature}]
+ @itemx --feature[=@var{feature}]
+ Activate miscellaneous @var{feature}. @var{feature} can be one of:
+ @table @code
+ @item caret
+ @itemx diagnostics-show-caret
+ Show caret errors, in a manner similar to GCC's
+ @option{-fdiagnostics-show-caret}, or Clang's @option{-fcaret-diagnotics}. The
+ location provided with the message is used to quote the corresponding line of
+ the source file, underlining the important part of it with carets (^). Here is
+ an example, using the following file @file{input.y}:
+
+ @example
+ %type <ival> exp
+ %%
+ exp: exp '+' exp @{ $exp = $1 + $2; @};
+ @end example
+
+ When invoked with @option{-fcaret}, Bison will report:
+
+ @example
+ @group
+ input.y:3.20-23: error: ambiguous reference: '$exp'
+ exp: exp '+' exp @{ $exp = $1 + $2; @};
+ ^^^^
+ @end group
+ @group
+ input.y:3.1-3: refers to: $exp at $$
+ exp: exp '+' exp @{ $exp = $1 + $2; @};
+ ^^^
+ @end group
+ @group
+ input.y:3.6-8: refers to: $exp at $1
+ exp: exp '+' exp @{ $exp = $1 + $2; @};
+ ^^^
+ @end group
+ @group
+ input.y:3.14-16: refers to: $exp at $3
+ exp: exp '+' exp @{ $exp = $1 + $2; @};
+ ^^^
+ @end group
+ @group
+ input.y:3.32-33: error: $2 of 'exp' has no declared type
+ exp: exp '+' exp @{ $exp = $1 + $2; @};
