In sysroot, I have glibc and glibc-devel. This worked with gcc 4.2 and with gcc
4.3 for every build, host, target combination except all linux-gnu. The most
interesting one is a build=linux host=mingw target=linux where sysroot contains
the exactly same files. This, as said already, works...
This should work at least because I use --with-sysroot and not
--with-build-sysroot.
