   /* The msys2 seems to make a buffer overflow of  EnvOfStackmachine[].
   The code
   [(x) ring_of_differential_operators 11] define_ring
   ( Dx*(x+Dx) ) /ff set
   causes the segfault because Mp_zero is borken. Is it a bug of msys2?
   Anyway, the following definition seems to be a workaround. 2015.09
   Singnals do not work properly on msys2. (gcc -dM -E ... to see macros defs)
