Compiling gcc with sysroot

[Christer Solskogen <christer.solskogen@xxxxxxxxx>]

Hi!

I've been reading the documentation for it, but quite don't understand. 
When gcc is compiled (and installed) with --with-sysroot=DIR (and prefix 
is set to the same) will that effect how gcc it self is built or the how 
the newly installed gcc will behave afterwords? or both?
