Marc:
I can't compile Meroon on darwin-ppc (I require more then 2GB of memory) with gcc after configuring gambit with the configure line
env CC='gcc -mcpu=970 -m64' ./configure
I could use an option to pull back the gcc compiler options to what they were before beta 20.
Also, you make the default compiler options pretty fancy now, but still -D___SINGLE_HOST is not the default. I'm wondering whether the default should be the previous set of compiler options and --enable- single-host. I think this would probably still give the best set of default options for both gcc and gsc.
