Hmm....  I thought the cross-gcc documentation was VERY specific about this, 
but I haven't looked at it in a while.  --with-headers is used only in a 
cross compiling environment.  It's used to point to a set of kernel headers 
that are already configured for the target you are interested in.  For 
example, you'll need to untar and patch a kernel for an ARM platform, let's 
say, then go in and do a 'make menuconfig' to select the 
machine/arch/whatever, then do a 'make dep'.  This ensures that the kernel 
headers and the links in include point to the right places.  I always do this 
first before starting to build a new tool chain just to make sure I don't 
forget...

Whenever I return from a trip abroad, I'm always amazed by two things:
All the wide open space we have in this country,
and how bad the roads are.
