I'm not terribly concerned about the uninstalling systemtap while compiling gcc problem. That seems like a package management problem on the distro side.
61257 does raise the issue of header file usability which is a much bigger concern. c#1 indicates autoconf-2.70 introduces code which instead of testing for header file existence instead checks for usability. So I'd rather see us moving towards making that happen rather than explicit enable/disable of systemtap headers/probes. jeff
