So, I've been trying to build gcc with --enable-objc-gc. At first I
thought the failure to build was simply due to random bitrot;
searching the list archives doesn't show anybody using this in quite
some time. But I finally realized that the build process is looking
for libobjc_gc.la but it's been built as libobjc_gc-gnu.la because the
Mac has its own (incompatible) libobjc installed so the -gnu is there
to avoid a conflict. So it's entirely possible that if I had another
system to test this on, it would work fine, which would also explain
the lack of anyone pointing out that it doesn't work. I tried to
patch around this myself, but my changes to libobjc/configure.in and
libobjc/Makefile.in don't seem to be getting noticed. (Yes, I re-ran
autoconf.) At this point I'm probably done trying, but if other
people want to have a look at this, here's how it fails...
This is with 4.2.0. I also tried with the latest out of svn from a
couple hours ago and got the same problem. I also tried last week
with 4.1.2.
