Provide minimum set of compatibility features required to run code in SICP.
This is a sort of "backburner" project---there's not much yet. Whatever you found missing, send PR.
Once we get enough meat, I'll bundle this to the Gauche distribution.
Clone the repo, or download zip and extract. Then:
$ ./configure
$ make install
Now, in gosh prompt or Gauche script you can use compat.sicp:
gosh> (use compat.sicp)
