I think an additional fix of this is in order:

diff --git a/lib/c-stack.c b/lib/c-stack.c
index c309666..9bbe6fe 100644
--- a/lib/c-stack.c
+++ b/lib/c-stack.c

 /* Output an error message, then exit with status EXIT_FAILURE if it

Rationale: There's an additional reference to 'die' in line 314,
with condition
  HAVE_SIGALTSTACK && HAVE_DECL_SIGALTSTACK && HAVE_STACK_OVERFLOW_HANDLING && !SIGINFO_WORKS
