embedding python -- windows specify problems

[John Pye]

Hi Fredrik,

Thanks very much for that reply. Your suggestion sounds feasible, I
guess. Taking what you said, and thinking about how I could avoid adding
an additional intepreter step, I thought that I could try the following:

	pyfile = PyFile_FromString(name,"r");
	if(pyfile==NULL){
		return 1;
	}	
	f = PyFile_AsFile(pyfile);		
	PyRun_AnyFileEx(f,name,1);

This seems to work on Linux at least (I'll test it tomorrow on my
Windows machine), and presumably it will work around the problem you
mentioned?

Cheers
JP
