Sure, I had to build the runtime (ie: linux glibc in my case) in order
to produce any binaries. And sure for that i had to have the glibc
source, so in a way I needed the runtime (in source form).

I realize too that my "solution" may not apply to Solaris (Solaris
libaries sources may not be available, or other problems). And that's
certainly not the simplest way for a Linux target either.

But this is possible, and maybe it is possible to for Solaris. May be it
is even possible to build glibc for Solaris this way.

The point is just than i'm trying to understand things about gcc
internals and I agree it isn't useful for the original poster and for
that I apologize.

(and I still think there is something not clear with the fact that when
I build with --with-newlib, i don't need newlib headers but i need glibc
headers otherwise)
