'lo,

Sorry, I should have been a bit clearer there. I mean if in the
very worst case, I can't get by with the system binutils, I can
create a "native" set of recent binutils using the cross-binutils
port:

  cd /usr/ports/devel/cross-binutils
  make TGTARCH=x86_64 TGTABI=freebsd7.2 install

That way, the port can just depend on those and I won't have to
create my own binutils port.

Like I said, I'm hoping this won't happen.

Current status is that I have a working native AMD64 GNAT using
2.19 binutils!

$ gcc44 -v

Needless to say, I'm pretty pleased.
