Do _not_ set CC. Add a symlink called "cc" or "cc.exe" pointing to
your gcc rsp. gcc.exe, instead.

This message looks as if you might be setting RTEMS_BSP=m68k-rtems.

--disable-tcpip does not exist. --disable-networking is probably
what you want.

Yep, here is the confirmation of my assumption above: This is wrong.

Simply do not use --enable-rtemsbsp, but use 
make RTEMS_BSP=<mybsp> after having run configure.

[<mybsp> is supposed to be one of the BSPs printed out at the end of
the configure run.]

Please use a different prefix instead with 4.5.0. Using
--prefix=/opt/rtems for building rtems interferes with the
toolchain's installation with 4.5.0 and after.
