Hi David,

do you recommend porting GDB to python3 (python-3.2, for Fedora 15)?

During my quick test [attached] the GDB python sources probably have to become
backward incompatible with python-2.x, do they have to?
	python2.7 ./python/python-config.py --libs
	  File "./python/python-config.py", line 15
	    file=sys.stderr)
	        ^
	SyntaxError: invalid syntax


Thanks for info,
Jan
