AC_DEFINE_UNQUOTED gives you an extra layer of resolution, but it might not be enough. The only workaround that I've found for this is to supply things via the command line (ie, -DFISH="@something@" in Makefile.in) - if that's possible with your scheme interpreter. If you find a solution, I'd like to know :) m.
