Interdependence of gcc to glibc/linuxheaders?

[Darin.Johnson at nokia.com]

I notice that during the builds of GCC it requires linux headers and actually copies headers and libraries from glibc.  Does this make GCC dependent later upon glibc and the particular linux headers?

In other words, after GCC is built, how difficult is it to replace everything with a different glibc, or uclibc, without having to recompile GCC?  If it's possible, which directories are safe to clobber and replace, and which need to be kept?
