/* 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)

#if defined(__MSYS__) || defined(__CYGWIN__)

#define setjmp(e) _setjmp(e)

#define sigsetjmp(e,n) _setjmp(e)

#endif
