-    examples/ucontext-cp.c: cope with variable SIGSTKSZ
-    
-    The size of C arrays at file scope must be constant. The following
-    compiler error occurs with recent upstream glibc (2.33.9000):
-    
-      CC ucontext-cp
-      ucontext-cp.c:31:23: error: variably modified ‘stack_buf’ at file scope
-      31 |         unsigned char stack_buf[SIGSTKSZ];
-         |                       ^~~~~~~~~
-      make[1]: *** [Makefile:26: ucontext-cp] Error 1
-    
-    The following glibc commit changed SIGSTKSZ from a constant value to a
-    variable:

-      ...
-      +# define SIGSTKSZ sysconf (_SC_SIGSTKSZ)
-    
-    Allocate the stack buffer explicitly to avoid declaring an array at file
-    scope.
