[GiNaC-devel] A smarter relational to Boolean conversion

[Vladimir V. Kisil]

	Dear All,

	I am attaching a small patch. With it the following conversions
  from relational to Boolean will become "true" from the current "false":

  realsymbol x("x");
  possymbol p("p");
  cout << bool(p>0) << endl;
  cout << bool(abs(x)>=0) << endl;

  Best wishes,
  Vladimir
