I didn't change cig, but I did scan all the scsh C
source. Outside of
userinfo1.c, I found no errorful code, although I
did armor-plate a few
other occurrences here and there, as well.
Great!
I forget if I sent this patch to you already. The way
dlopen() reports an
error seems to have changed at some point, and FreeBSD
now does it the way
the rest of the world does. (It now returns 0 instead
of -1.) I wouldn't
be surprised to find that NetBSD now works this way as
well. I don't know
if it is worth doing the autoconfig work needed to
make the old way
continue to work in the older Unix versions.
Hmmm... This is actually a Scheme48 bug isn't it.
What's your policy on
that? Do you want them to fix it first, or are you
willing to include
Scheme48 fixes in scsh?
I've CC'd this message to scheme48-bugs because I
don't rememebr if I've
reported this to them either...
