+Subject: Fix compilation with gcc 6

+The compiler emits:
+MathStructure.cc: In function 'bool sr_gcd(const MathStructure&, const MathStructure&, MathStructure&, std::vector<sym_desc>::const_iterator, const EvaluationOptions&)':
+MathStructure.cc:7166:53: error: no matching function for call to 'MathStructure::gcd(MathStructure&, MathStructure&, MathStructure&, const EvaluationOptions&, bool)'

+                                                     ^
+In file included from MathStructure.cc:14:0:
+MathStructure.h:827:15: note: candidate: static bool MathStructure::gcd(const MathStructure&, const MathStructure&, MathStructure&, const EvaluationOptions&, MathStructure*, MathStructure*, bool)

+Pass down NULL instead of false.
