Hi,
I've just installed Mac OS X 10.6, aka "Snow Leopard", on a partition on
my Mac (Intel Core 2 Duo, which probably means 32 bit only), and I was
curious to see what the consequences might be for Pico Lisp. I downloaded
the ongoing dev. version of Pico Lisp and did the usual "(cd src; make
picolisp)". The results weren't too nice, but I'm not sure what the
problem is:
$ (cd src; make picolisp)

I also tried building Pico Lisp 2.3.5, but got the same as above. However,
running the Pico Lisp 2.3.5 that I built using Mac OS X 10.5.x, went fine,
including my OpenGL Chinese Checkers.
Snow Leopard does bring some changes re. gcc. Some info may be found here:
