I would add "--program-prefix=m68k-elf-" to your configure arguments, but I don't think it is mandatory.

Yep, that looks OK.  I'm pretty sure that it looks in $prefix/$target/include for header files and $prefix/$target/lib for library files.

When I use newlib, I use the --with-headers option instead of copying them.  The "make" or "make all" step will install them to the right place.  Try "--with-headers=<newlib-path>/newlib/libc/include" in your configure arguments.

PS. I haven't tried gcc-2.95 yet and I have only built cross-compilers for powerpc-linux and powerpc-eabi targets.
