@defmac MUST_USE_SJLJ_EXCEPTIONS
This macro need only be defined if @code{DWARF2_UNWIND_INFO} is
runtime-variable. In that case, @file{except.h} cannot correctly
determine the corresponding definition of @code{MUST_USE_SJLJ_EXCEPTIONS},
so the target must provide it directly.

@defmac DONT_USE_BUILTIN_SETJMP
Define this macro to 1 if the @code{setjmp}/@code{longjmp}-based scheme
should use the @code{setjmp}/@code{longjmp} functions from the C library
