By "Suns" do you mean Sparc or 68k?  You need to build a cross-compiler
for anything other than a PC running OS/2 or a Sparc running SunOS.

Also, you need to install the GCC you build, specifically the
driver program.

That's correct once you install the driver program (gcc).

The file name are set up to work on PC's as well.  Therefore, GNAT must
be told to use the shortened file name, hence -k8.  This affects the
current compilation, not what the compiler being built supports.
