[GiNaC-devel] pseries patch

[Vladimir Kisil]

		Dear All,

		I come across an inability of GiNaC to compute simple series,
  e.g. in the following example:

#include <iostream>
#include <ginac/ginac.h>
using namespace std;
using namespace GiNaC;

int main(){
	possymbol t("t");
	cout << pow(2-sqrt(1-t), -1).series(t==0,2) << endl;
	cout << pow(1-sqrt(1-pow(t,2)), -1).series(t==0,2) << endl;
}

 A simple patch included in the attachment seems to solve the issue.
 
 Best wishes,
	  Vladimir
