-+Some C interfaces to Fortran codes violate the gfortran ABI by
-+omitting the hidden character length arguments as described in
-+@xref{Argument passing conventions}.  This can lead to crashes
-+because pushing arguments for tail calls can overflow the stack.
-+
-+To provide a workaround for existing binary packages, this option
-+disables tail call optimization for gfortran procedures with character
-+arguments.  With @option{-ftail-call-workaround=2} tail call optimization
-+is disabled in all gfortran procedures with character arguments,
-+with @option{-ftail-call-workaround=1} or equivalent
-+@option{-ftail-call-workaround} only in gfortran procedures with character
-+arguments that call implicitly prototyped procedures.
-+
-+Using this option can lead to problems including crashes due to
-+insufficient stack space.
-+
-+It is @emph{very strongly} recommended to fix the code in question.
-+The @option{-fc-prototypes-external} option can be used to generate
-+prototypes which conform to gfortran's ABI, for inclusion in the
-+source code.
-+
-+Support for this option will likely be withdrawn in a future release
-+of gfortran.
-+
-+The negative form, @option{-fno-tail-call-workaround} or equivalent
-+@option{-ftail-call-workaround=0}, can be used to disable this option.
