Hello,
Today I noticed that some of my code that works on the
Debian packaged version of GCL doesn't work with the latest
git checkout (master branch, 955c7fa7..., Thu Sep 13 16:32:27).
This is what happens: I check the type of variables that
have content generated by gensym, and so far I thought that
(type-of (gensym)), of, for that matter, (type-of x), where
x contains the return value of (gensym), would always be
SYMBOL. But it is not anymore:
$ GCL_ANSI=1 gcl

>(type-of (gensym))
SYSTEM:GSYM
I configured GCL as:
./configure --enable-ansi
--enable-readline
--enable-notify=yes
--enable-emacsdir=/usr/local/share/emacs/site-lisp
--mandir=/usr/local/share/man
--enable-infodir=/usr/local/share/info
The debian version (2.6.12-80 in sid/unstable) returns "SYMBOL"
(ECL, Clisp, CCL and SBCL also return SYMBOL).
Is this a planned change for the next release? Or is it a bug?
(Shouldn't GSYM be a subtype of SYMBOL, perhaps?)
Thanks a lot,
J.
