Camm:

Lawrence fixed the Macports port of GCL-2.6.12 so I was able to install it.

The next thing, though, is that GCL appears not to be work properly with
Clang on this platform -- Clang is the default system compiler on new
versions on Mac OS X.

For example, I tried to build OpenAxiom with it, but was stumped by:

Finished compiling core.lisp.

gcl \

-eval '(load "core")' \

-eval '(|AxiomCore|::|link| "base-lisp" (quote nil)
"|AxiomCore|::|topLevel|")'

Unrelocated non-local symbol: ___stack_chk_fail


Error:

Fast links are on: do (si::use-fast-links nil) for debugging

Signalled by LOAD.

Condition in LOAD [or a callee]: INTERNAL-SIMPLE-ERROR: The assertion

Broken at LOAD.  Type :H for Help.

    1  Return to top level.

Clang is also unhappy that GCL is declaring standard C functions instead of
including the appropriate headers, plus some other stylistic issues:

; Note: Tail-recursive call of |processCommandLine| was replaced by
iteration.

;; Note: Tail-recursive call of |processCommandLine| was replaced by
iteration.

End of Pass 2.

I know you worry about including standard headers, but the world is moving
in that direction...
