Ok. I've added the following lines to scripts/mgnuc.in at about line 392 
(it's the code dealing
with pathological architectures):

         *-apple-darwin*)
                 # cpp-precomp gets big and slow. Avoid.
                 case "$COMPILER" in
                         cc | gcc)
                                 GCC_OPTS="$GCC_OPTS --traditional-cpp"
                                 ;;
                 esac
                 ;;

It seems to have done the trick i.e. I'm now getting reasonable compile 
times.

Notes:

[1] *-apple-darwin* used because there's noise about an Intel port of 
Darwin.
[2] I don't know what flow on this change will have. There's a comment 
about
      mirroring changes in ../configure.in but I couldn't see anything 
appropriate to fix
      or change in that file.

Take care,

richard
