	Better associating the headers with each GCC release sounds like a
fine idea.  I am a little concerned about placing the G++ headers with the
"fixed" system headers and support files.  That location contains
target-dependent data, so it precludes sharing the common headers among
targets.  I can sympathize that another target-triplet/version directory
hierachy would be cumbersome if the version is not sufficient.

	I worry that the headers will be hard to find and browse; it
almost seems like the headers are being hidden.  Maybe a symbolic link
from $prefix/include could be provided for the latest installation?
