I think I figured out a way of getting the stuff out of GCC.
This command:

  echo -n | gcc -S -x c - -o - | grep -v '\.\(file\|ident\|section\)'

gives me some useful-looking output on the only ARM box I have.
So for standalone I8C I'll try doing something equivalent to
generate the required directives.  Probably a little hacky, but...

For GLIBC I'll add an option to suppress the automatic preamble
discovery and use -include to suck in sysdeps.h to make sure
I'm getting it exactly right for whatever target is in use.

Thanks for your help,
Gary
